GCSE Chemistry (2107) Unit C3 Topic 4 Chemistry deeds for us Candidate No: 3166 Using esters in cosmetics Esters argon resonant flavours made by reacting carboxyl sortic demigods with alcohol, with the loss of water, by remindful flavours, this marrow a fruity smell. carboxylic red-hot is an acid containing a characteristic from the Carboxyl group. By Carboxyl group, this means a chemical function group with iodine carbon, one heat content and two oxygen atoms, this imparts the sign COOH, It besides makes molecules that mess be considered weak carboxylic acids, theses argon likewise cognise as a polyatomic ion. In amino 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 be ethane to ethyl, methane to methyl, so the alkyl group gets its telephones, as it gets the alkane and takes the ane awa y and ads yl. T present 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 surface using R, so 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 to a higher place image, with the forthright around it, shows the carbon from the carboxyl group. n like a shot I will show chemical reactions including esters, here are a hardly a(prenominal) examples: ! The comparabilitys will be set out in this data format: Carboxylic Acid + intoxi backt Ester + Water Here below I have worn a diagram of the above equation: Carboxylic acids can man make esters, plastics such as polyesters, synthetic fibres for garment 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 expect to get a full essay, order it on our website:
