Question
What hydrolysis products are formed when the wax CH3(CH2)18COO(CH2)17CH3 is treated with aqueous sulfuric acid? Group of answer choicesCH3(CH2)18COOH + CH3(CH2)16CH2OHCH3(CH2)18CHO + CH3(CH2)16CH2OHCH3(CH2)18COOH + CH3(CH2)16CH3CH3(CH2)18COOH + CH3(CH2)16COOHCH3(CH2)18CH2OH + CH3(CH2)16COOH
Solution
The wax CH3(CH2)18COO(CH2)17CH3 is an ester. When an ester undergoes hydrolysis in the presence of an acid such as sulfuric acid, it breaks down into a carboxylic acid and an alcohol.
The carboxylic acid is formed from the carbonyl part of the ester (CH3(CH2)18COO) and one hydrogen ion from the water. This gives CH3(CH2)18COOH.
The alcohol is formed from the alkyl part of the ester (CH2)17CH3) and the hydroxyl group from the water. This gives CH3(CH2)16CH2OH.
So, the hydrolysis products formed when the wax CH3(CH2)18COO(CH2)17CH3 is treated with aqueous sulfuric acid are CH3(CH2)18COOH and CH3(CH2)16CH2OH.
