The addition of ethyl alcohol in protonated acetic acid is:
Correct answer: C. Nucleophilic acyl substitution
- A. Electrophilic substitution
- B. Nucleophilic addition
- C. Nucleophilic acyl substitution
- D. Oxidation
Explanation
This describes a key step in the Fischer esterification mechanism. The alcohol acts as a nucleophile, attacking the protonated carbonyl carbon. This is followed by the elimination of a water molecule, which is characteristic of a nucleophilic acyl substitution.

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.
