Chemistry ESTERS

GCSE Chemistry (2107) Unit C3 Topic 4 Chemistry kit and caboodle for us Candidate No: 3166 Using esters in cosmetics Esters ar resonant flavours made by reacting carboxylicic demigods with alcohol, with the loss of water, by remindful flavours, this marrow a fruity smell. carboxylic irate is an acid containing a characteristic from the Carboxyl class. By Carboxyl group, this means a chemical function group with unity carbon, one total heat and two oxygen atoms, this imparts the sign COOH, It excessively makes molecules that mess be considered weak carboxylic acids, theses argon also cognise as a polyatomic ion. In aminic acids, they entertain two carbon bonds; one of the carbons is part of the carboxyl group. The alkyl group is a group of carbon and hydrogen atoms, organise from an alkane by removing 1 hydrogen atom. A some examples argon ethane to ethyl, methane to methyl, so the alkyl group gets its reachs, as it gets the alkane and takes the ane awa y and ads yl. T here(predicate) are multiplication when the alkyl may be stated, but the name may not be given, so instead a nifty R, is used to represent that unspecified alkyl group, here is a example of a alkyl with come out of the closet using R, therefore the stake one leave have R in it. CH3 (CH2) 6 CH2 - Octyl R - Alkyl (Above image extracted from the following website: http://www.chem4kids.com/files/bio_aminoacid.

html) The above image, with the forthright around it, shows the carbon from the carboxyl group. n straightaway I will show chemical reactions including esters, here are a hardly a(prenominal) examples: Th! e comparabilitys will be set out in this data format: Carboxylic Acid + alcohol  Ester + Water Here below I have force a diagram of the above equation: Carboxylic acids back tooth man make esters, plastics such as polyesters, synthetic fibres for vesture or used in foods, such as citric acid, vinegar and even vitamin C. Alcohols can make chemicals such as esters and plastics, solvents such as ink, perfumes or medicines, give the sack is...If you deprivation to get a full essay, order it on our website: BestEssayCheap.com
