SYNTHESIS SUMMARY Thesis: The GSAT examination should be addressed as an inadequate measure of scholastic ability and‚ hence‚ is unsuitable as the main tool used in the current academic system. Two recent articles have shed light on the public consensus showing displeasure with the GSAT examination. The first article‚ by Tyrone Reid GSAT ‘Unsuitable’ published in the Gleaner on Monday April 6‚ 2012‚ speculates at the appropriateness of the content of the exam and also its strict means

Writing a Synthesis Essay/Paper A synthesis essay draws on two or more sources and combines their ideas into a coherent whole. The word "synthesis" means to combine related things in a meaningful way‚ with a specific purpose in mind. When you synthesize‚ you blend the parts in such a way that you create something that is worth more than merely the sum of the parts. For our purposes‚ synthesis means putting together the arguments of various authors in a way that sheds new light on the discussion

Synthesis of Chloroform -------------------------------------------------------------------------------- With Calcium Hypochlorite and Acetone When chlorine is passed into boiling alcohol‚ both chlorination of the methyl group and oxidation of the primary alcohol group to an aldehyde occur‚ giving trichloro-acetaldehyde or chloral: When chloral is treated with caustic alkali‚ fission of the C-C linkage occurs‚ giving chloroform and a formate. Acetaldehyde and also many ketones‚ such as acetone

Traditional way of synthesizing sensitive rhodamine starts with rhodamine B‚ amino compound‚ and some alkali additive in the presence of weak base. However‚ for RH-PY‚ the stearic hindrance of pyrene slows the reactivity‚ and the reaction does not go to completion. Therefore‚ the reaction procedure was modified as follows. First‚ HATU and DIPEA were used to activate the carboxyl group of rhodamine B‚ then the activated rhodamine B was reacted with 1-aminopyrene. By introducing this method‚ the reaction

Introduction: The purpose of this lab was to learn how to use salicylic acid to make aspirin. Aspirin is the most widely used over-the-counter drug in the world. The average tablet contains about 325 milligrams of acetylsalicylic acid with an inert binding material such as starch. Aspirin is used to relieve pain‚ reduce inflammation‚ and lower fever. Aspirin originally was derived by boiling the bark of the white willow tree. Although the salicin in willow bark has analgesic properties‚ purified
