Organic Chemistry Hydrocarbon Nomenclature Prefixes

Organic Chemistry Hydrocarbon Nomenclature Prefixes The purpose of organic chemistry nomenclature is to indicate how many carbon atoms are in a chain, how the atoms are bonded together, and the identity and location of any functional groups in the molecule. The root names of hydrocarbon molecules are based on whether they form a chain or ring. A prefix to the name comes before the molecule. The prefix of the molecules name is based on the  number of carbon atoms. For example, a chain of six carbon atoms would be named using the prefix hex-. The suffix to the name is an ending that is applied that describes the types of chemical bonds in the molecule. An IUPAC name also includes the names of substituent groups (aside from hydrogen) that make up the molecular structure. Hydrocarbon Suffixes The suffix or ending of the name of a hydrocarbon depends on the nature of the chemical bonds between the carbon atoms. The suffix is -ane if all of the carbon-carbon bonds are single bonds (formula CnH2n2), -ene if at least one carbon-carbon bond is a double bond (formula CnH2n), and -yne if there is at least one carbon-carbon triple bond (formula CnH2n-2). There are other important organic suffixes: -ol means the molecule is alcohol or contains the -C-OH functional group-al means the molecule is an aldehyde or contains the OC-H functional group-amine means the molecule is an amine with the -C-NH2 functional group-ic acid indicates a carboxylic acid, which has the OC-OH functional group-ether indicates an ether, which has the -C-O-C- functional group-ate is an ester, which has the OC-O-C functional group-one is a ketone, which has the -CO functional group Hydrocarbon Prefixes This table lists the organic chemistry prefixes up to 20 carbons in a simple hydrocarbon chain. It would be a good idea to commit this table to memory early in your organic chemistry studies.

For example,  (CH3)2CHCH2CH2Br is named 1-bromo-3-methylbutane. Common Names Be aware, hydrocarbons found as rings (aromatic hydrocarbons) are named somewhat differently. For example, C6H6 is named benzene. Because it contains carbon-carbon double bonds, the -ene suffix is present. However, the prefix actually comes from the word gum benzoin, which as an aromatic resin used since the 15th century. When the hydrocarbons are substituents, there are several common names you may encounter: amyl: substituent with 5 carbonsvaleryl: substituent with 6 carbonslauryl: substituent with 12 carbonsmyristyl: substituent with 14 carbonscetyl or palmityl: substituent with 16 carbonsstearyl: substituent with 18 carbonsphenyl: common name for a hydrocarbon with benzene as a substituent

Flannery O'Connor's A Good Man is Hard to Find Essay - 1

Flannery O'Connor's A Good Man is Hard to Find - Essay Example The Grandmother is very irritating woman. During the car ride, she lies about the dimensions of a house just to make it sound more interesting to the children. And when she realizes that the house she’s been bragging about is not even in that state, she panics and kicks the cage holding the cat. She doesn’t do that on purpose. She is annoying but she doesn’t deserve to be shot three times in the chest. In fact she tries to make a connection with the Misfit during the confrontation and when she feels sorry for Misfit and about the way he has been treated all his life, she tries to physically touch him and at that moment Misfit’s henchmen shoot the old woman. It is very true that many people only claim to be Christians but in the dealings of their lives, their behavior, their conduct and their daily conversations are devoid of the spirit of Christianity. The grandmother is blessed with a loving son but she is not thankful for it and doesn’t actually care about him. In fact she treats him as a tool and takes advantage of his obedience. In the book, after the car accident Misfit and his men seize the family and they take family members in the woods and shoot them. Seeing her fate very clear the grandmother suddenly remembers God and Jesus and turns soft. She asks Misfit to pray so that his soul may be spared for the sins he has committed all his life. A very religious and philosophical conversation takes place towards the end of the story between the Misfit and the Grandmother, where Misfit tries to mock Jesus by saying that he created a lot of confusion by raising dead people (in hidden words, he mocks the whole concept of heaven a nd hell and the day of judgment). To this, grandmother agrees somewhat by saying that probably he didn’t raise the dead after all but when she gets shot in the chest, she falls down with her legs crossed in to her grave, representing her faith in a dramatic and symbolic way.

Marketing - Research Paper Example Threat of Substitute The food drinks mainly represent the fast moving consumer goods market and therefore the markets mainly rely on creating impulse purchase. Price sensitivity is quite low in the market; mainly marketers mainly rely on customer loyalty and brand loyalty. There are a lot of products that can provide boost and act as replacement to the energy drinks. Due to the nature of the product the target customers may switch to soft drink and carbonated drinks. Also the customers have a lot more health conscious. Therefore the customers may also look to drink lot of fluids such as herbal tea and water. Hence, there are a lot of alternative options for the customers. Overall, the level threat of substitute of products is high. Bargaining Power of Suppliers While considering the bargaining power of the buyers from the perspective the energy drink market only it can be interpreted that the bargaining power of the buyer would be quite low as there are very few players in the market . Also buyers in the market are not very price sensitive as the products are targeted towards the higher end market. The relation between the manufacturer and retailer has also evolved over the course of the market life cycle. However, the buyers should be wary of the fact that there are a lot of substitute products in the market (Williamson, Cooke and Jenkins, 2004). Bargaining power of Buyers The production process to develop the energy drinks is quite simple and bargaining power of the suppliers is quite low. The supply chain of the top players in the market is quite short. The value added in each and every stage of the production process leads to significant level of profit. The only access to the attractive market for the suppliers is through the brand owners. All in all as there are small numbers of players in the market the bargaining of the suppliers is quite low (Brown, 2009). To summarize thing it can be said that the competition level competition in market is moderate as there as few players in the market. The threat of new entrants varies between medium to high as it is likely that more and more competitors would look to enter the market due to the high level of profit. However, the economies of scale, high level of brand loyalty and the recent economic downturn would act as a major barrier to entry. The bargaining power of the suppliers and the buyers is low as there are very players in the market. However, the major threat for would be the presence of various substitute products (Kolb, 2008). Industry Rivalry The market is mainly dominated by companies like GSK and Red Bull. Lucozade is a brand of GSK. These companies have made the market saturated. The market has moved from being a niche market to mass market. It is most certainly a market for the multinational companies. Familiarity of brands would definitely play a key role to play in gaining competitive advantage. Also product dedifferentiation would play a key role. Already Lucozade has been successful in achieving product differentiation through the introduction of the caffeine versions. One of the recent entrants in the market has been the Taut, which has looked to position itself as a clean sports drink. Due to high industry margins, large of companies have looked to enter the market; but the rivalry among the brands have no lead to any kinds of adverse conditions. Although some of the smaller players have tried to imitate the strategies of Lucozade and Red

Management - Essay Example This theory is also based on another theory known as cognitive evaluation theory according to which a person loses interest in his work because of the external factors such as increase in pay etc. This can be explained in other words as the decrease in the motivation of a person to work gradually decreases as the number of incentives being provided to him increase because people get the perception that the work they are doing is forced and compulsory and hence, the person loses interest in doing the same work because then he feels that it is his duty. Another theory, the goal setting theory explains the importance of setting goals and how it improves the performance of an individual. This theory also proves that when a person is told about what goals to achieve and when to achieve it, he automatically works on the task in order to reach his goal. Similarly, if a person is appreciated for his works, his performance eventually increases to a great extent. But a big factor regarding thi s theory is the acceptance of the set goal. And harder goals gave better performances as compared to easier goals. The third theory, known as self efficacy theory or social learning theory is based upon the thinking of an individual whereby he thinks that he has the ability to achieve certain goals or tasks. Hence, if a person is less efficacious he is more prone to give up easily, whereas someone who is highly efficacious will try his best to accomplish the task. The most widely accepted theory is known as expectance theory in which a person seems to think that if he performs better he will be rewarded for it and hence his performance is greatly affected due to this thinking. The manager told that motivating employees was one of the most important parts of any organization and special attention is given to make sure that the employees are motivated to the best level possible. The leader appreciated each and every employee individually

A Doll's House by Henrik Iben Essay Example | Topics and Well Written Essays - 1500 words

A Doll's House by Henrik Iben - Essay Example Most of Henrik Ibsen’s plays revolve around the struggling of people for an authentic identity for themselves. The backdrop of this struggle is a tyrannical society in which individuals struggle between their duty towards themselves and towards their families and society in general. One such woman is our protagonist Nora who represents such women who are repressed by society. Nora’s husband is Torvald Helmer, who is a rather controlling type of individual and treats her as one of his responsibilities and he is the one that portrays her identity. Most women in those days were not educated and so were easily relegated into a corner and never came out to voice their opinion. In this deductive essay, we are going to make an investigation on the theme of identity and how it was reflected in ancient society. Women in the 19th century were expected to be the typical stereotype subservient housewife, but one would be surprised at the turn of events in Henrik Ibsen’s play . Nora Helmer, who is the chief protagonist of this play, has all the characteristics of this stereotype woman, who does not possess an identity of her own and hence is depicted as an oppressed individual who possesses an inauthentic identity because of the societal demands of those times. In the beginning Nora is seen responding to her husband’s teasing and does not seem to care about her doll- like existence and with no identity to call her own. In sharp contrast to Nora, we have the contemporary woman of today with a world of difference in their attitudes and reactions to such a situation. Modern women in our present society has her own identity because she has made herself so strong, powerful and full of confidence in all that she does. However, as the play progresses we find Nora shedding some of her inauthentic identity by playing a more specific role in the family. The author highlights various facets of her intelligent and courageous nature which is far from the †Å"silly girl† her husband made her out to be. One such incident that was highlighted was the loan she had taken to preserve her husband’s health after forging her father’s signature, which proved that she was quite intelligent and possessed qualities that were beyond mere wifehood. However, Nora was quite inexperienced in many ways and did not understand the ways of the world, because she always lived under the care of her father and later on her husband. This statement is very clear when she tells her husband Torvald in no uncertain terms that, "I've been your wife-doll here, just as at home I was Papa's doll-child."(1608) However, as the play progresses, we find a great change taking place as Nora emerges as a strong and confident individual who refuses to be a doll any longer and rejects the false union of marriage and the burden of motherhood. This image of Nora identifies with the image of today’s strong and confident women, who like to live life acco rding to their own terms and not remain a scapegoat to be targeted at all times. The changing phase of Nora, is further augmented when she connects once again with her childhood friend Mrs. Linde who suffers the loss of her mother and husband. Mrs. Linde was a very down to earth person whose life was a big struggle due to poverty. Her adherence to the norms of society provides a perfect foil to the impetuous nature of Nora. Linde is a perfect foil to Nora’s lively exuberance in addition to her feminist ideas which explode towards the end of the play. Mrs. Linde is an archetype of the woman of those days, whose qualities Michael Meyer has described as â€Å"stuffy Victorianisms. Kristine Linde is in fact a sharp contrast to

Ethical Issues in HRM Strategy Essay Example | Topics and Well Written Essays - 750 words

Ethical Issues in HRM Strategy - Essay Example Thus, the rewards of practicing effective HRM practices are inevitable just as the dire consequences of sidestepping HRM principles are sure. Question 1 The area that overlaps in the new client organization with others that I have served in has to do with organizational performance. Herein, other areas such as creating a feasible performance target, carrying out performance appraisal, and establishing the best way for sealing performance gap emerge. This overlap is underpinned by the fact that performance is the main reason for general organization existence. Creating a performance target directly relates to all organization’s goals, vision and mission statement. Performance appraisal, on the other hand, will help determine whether an organization has hit its target or not, at the end of a fiscal year. Question 2 There are certain ethical issues that may accost the ratification of expert knowledge of other organizational HRM strategies with the new client. Particularly, the pr oposition that the client organization downsizes some of its staff to avoid redundancy and as part of closing the performance gap readily brings ethical concerns. This may mean that there are many who are going to forfeit their source of livelihood, their input in and experience with the client organization notwithstanding. Similarly, the signing of performance contracts may also underscore the ethical concern above since an employee’s security of tenure will be pegged on his performance. Conversely, persuading a part of the staff to embrace workshop and training programs may be an ethical challenge, given that some in this section may be older, both in terms of age and tenure in the client organization. At the same time, workshop drives and training programs may eat into employees’ private and family lives if study travels are involved (O'Higgins & Kelleher, 2005). Question 3 One of the best approaches to customizing HRM strategy to business strategies is the incorpor ation of HRM strategies into the business organization’s mission statement, objectives and strategy. By doing this, the business organization’s synergy will be extended and channeled towards the fulfillment of the client organization’s mission statement and long-term objectives. At the same time, the modus operandi that the business organization will be using is one that will be in tandem with HRM strategies. Some of these strategies that an organization may incorporate into its performance strategies may include the signing of performance contracts, introducing and observing workshop drives and training programs, and using behavioral techniques which portend the introduction of rewards (for diligent and committed employees) and punishment (for employees who consistently and knowingly disregard due diligence and proper workmanship) (Valentine & Hollingworth, 2012). As Caldwell and Truong (2011) suggest, another way by which HRM strategies can be customized to bu siness strategies is by making HRM strategies part of the organizational hierarchy. This means that the human resource manager must feature among other top echelons of the organization such as finance, marketing, corporate planning, supply chain management, sales and management. At the same
