Carboxylic Acid and Derivatives

Chinese General Hospital Colleges First semester, AY 2013 2014 Organic Chemistry (Laboratory) Experiment no. 10 Date performed: September 5, 2013 Group 3 Names: Date submitted: September 19, 2013 De Gunman, Joanna Claries Del Mound, Marilyn Dells Rexes, Pamela L. Deal Cruz, Married Cyril M. Duran, Zenith Anne P l. Theoretical background Carboxylic acid derivatives are organic compounds containing the call group core structure attached to a Y group, which may be an electronegative atom or substitutes. The Y group acts as a leaving group in necrophilia call substitution. This mechanism is involved in hydrolysis, alcoholisms, and analysis reactions. As strong organic acids, carboxylic acids react with silver nitrate and sodium bicarbonate to form the corresponding carboxylic salts. Among the carboxylic acid derivatives, call halides are the most reactive and amides the least. Thus, the reactions of these compounds with a given reagent vary with regard to the rate, thermometric, and even the completion of the reaction. Call chlorides, due to their reactivity, are good starting materials for synthesis. Esters and amides are important functional groups in bimolecular like fats and proteins. All carboxylic acid derivatives yield the parent carboxylic acid upon reaction with water. Moreover, one derivative can be converted into another, provided the former is more reactive than the latter. II. Objectives To differentiate the reactivates of carboxylic acid derivatives. To distinguished carboxylic acid derivatives using classification tests To explain through chemical equations and mechanisms the reactions involved in each test. Ill.

Consumer Behavior Final Campaign Essay Example | Topics and Well Written Essays - 2000 words

Consumer Behavior Final Campaign - Essay Example Because of this particular target market, Samsungs product offering to these individuals is necessarily high tech, cutting-edge, sleek, attractive, and expensive. By means of contrast in comparison, the target market that exists within lesser developed regions of the world, namely South America, many parts of Africa, and regions of Asia, is significantly different. Utilitarianism and functionality is the main concern that this target market represents. Beyond this, durability and low cost are other metrics that are highly appreciated within the aforementioned – lower income regions of the globe. Because of this, Samsungs target market within these areas is specifically predicated upon a larger segment of society; one that represents youth as well as individuals of a more advanced age. Similarly, as the income gap is far wider within these particular regions, and for individuals make up a statistically larger percentage of the overall population, the target market is specifical ly directed towards those that are not able to afford the more high-end and technologically advanced product offerings that Samsung is otherwise known. As a result of this fact, the product, as well as the target market, it is differentiated as compared what has already been discussed.

Medical Mentoring - Essay Example Since there is a rarity of women in several elite fields in medicine, which reduces their chances of getting mentorship or sponsorship in these sub-fields, women are rarely inducted into these fields. Most female medical students have wondered whether there are women in some fields of medicine for them to contact. In addition, there was also a feeling that female medical students could mentor undergraduate female students; especially the undergraduate students interested in science, but short on ideas and encouragement (DeLaat, 2007). However, the issue of what mentors would get out of mentoring female students came up, to which the contended that hospitals and institutions must recognize how important mentorship is, especially as the unequivocal support from senior management or organizational leaders for the concept of sponsorship and mentoring. This will encourage mentors to consider a serious mentorship, while allowing the professional time to support the programs (DeLaat, 2007). From this case study, it is clear that gender has a major role to play when it comes to the expectations of female students with regards to mentoring, while also having an influence on their career planning. Optimal relationships in sponsorship and mentoring are relational, while relational mentorship is more crucial compared to gender concordance (Humphrey, 2010). In addition, power dynamics, which are gender-based, have a greater influence on the thinking of students concerning mentoring. Stereotypes and assumptions based on gender also have a significant effect on sponsorship and mentoring relationships. Successful relationships in mentoring can only occur when the mentors in the faculty, whether female or male, attempt to take the time required to know the students on a personal level, as well as to know the students from a career point of view. From the case study, it seems that the female medical students and physicians have gender expectations that they will relate better to female mentors, who will also be more supportive compared to male mentors. This could be because male mentors are more content focused, direct, and less comfortable when discussing with female students on work-life balance (Humphrey, 2010). From the case study, it also seems that those attending the seminar believe that the gender of the mentee will affect the advice that they are given with regards to choices of career. The students may also wish to go beyond stereotypes of gender when interacting with the mentors (Humphrey, 2010). A perception exists where the gender of female students may potentially hinder their sponsorship opportunities and networking, as well as the perception that mentors of the female gender are not in a position to provide the access female students require to vital networks. However, while the case study does not provide enough evidence whether this is the case, it is clear that there is a need for more female mentors with experience, as well as for women holding powerful positions in medicine, particularly in fields that are dominated by women. While the case study was mainly focused on female students in medical school, the mentee and the
