Q15 / 90 · JEE Main 2022 (29 Jun Shift 1) · Chemistry

Given below are two statements :

Statement I: The esterification of carboxylic acid with an alcohol is a nucleophilic acyl substitution.

Statement II: Electron withdrawing groups in the carboxylic acid will increase the rate of esterification reaction.

Choose the most appropriate option

  • A
    Statement I is correct but Statement II is incorrect.
  • B
    Both Statement I and Statement II are incorrect.
  • Correct answer
    C
    Both Statement I and Statement II are correct.
  • D
    Statement I is incorrect but Statement II is correct.

Solution

Figure

In the above reaction OH group is replaced by OR group. Hence, nucleophilic substitution reaction is involved. Electron withdrawing groups increases the stability of RC⊕OH2, hence, rate of reaction increases.

Hence, the correct answer is option: 'C'.
