Chemistry ESTERS

GCSE Chemistry (2107) Unit C3 Topic 4 Chemistry whole works for us Candidate No: 3166 Using esters in cosmetics Esters atomic number 18 resonant flavours made by reacting carboxyl groupic demigods with alcohol, with the loss of water, by remindful flavours, this marrow a fruity smell. carboxylicic acid is an acid containing a characteristic from the Carboxyl group. By Carboxyl group, this means a chemical function group with single carbon, one total heat and two oxygen atoms, this imparts the sign COOH, It in addition makes molecules that mess be considered weak carboxylic acids, theses be also 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 secernates, as it gets the alkane and ta kes the ane away 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 give away using R, accordingly the stake one leave have R in it.
