To prepare ethyl alcohol, the ester that can be hydrolysed is:

Correct answer: D. Ethyl formate

  • A. Methyl formate
  • B. Methyl acetate
  • C. None of these
  • D. Ethyl formate

Explanation

Ethyl formate is the correct ester that can be hydrolyzed to produce ethyl alcohol. The hydrolysis reaction of ethyl formate with water results in the formation of ethyl alcohol and formic acid:HCOOCH2CH3 + H2O → CH3CH2OH + HCOOHThe other options, methyl formate and methyl acetate, produce methanol when hydrolyzed, not ethyl alcohol. Therefore, they are incorrect in the context of this question.

About Carboxylic Acids

Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
