Unit C3 Topic 4 Chemistry workings for us
Candidate No: 3166
Using esters in cosmetics
Esters are resonant flavours made by reacting carboxylic demigods with alcohol, with the loss of water, by remindful flavours, this marrow a fruity smell. Carboxylic acid is an acid containing a characteristic from the Carboxyl group. By Carboxyl group, this means a chemical function group with one carbon, one hydrogen and two oxygen atoms, this imparts the sign COOH, It also makes molecules that mess be considered weak carboxylic acids, theses are 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 are ethane to ethyl, methane to methyl, so the alkyl group gets its names, as it gets the alkane and takes the ane away and ads yl. There 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 without using R, then the stake one leave have R in it.
CH3 (CH2) 6 CH2 - Octyl
R - Alkyl

The above image, with the forthright around it, shows the carbon from the carboxyl group.

Now 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 + Alcohol Ester + Water
Here below I have drawn a diagram of the above equation:
Carboxylic acids can man make esters, plastics such as polyesters, synthetic fibres for clothing 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 want to get a full essay, order it on our website: Orderessay
