JEE Main 2025 — 8 April, Evening Shift — Question 16

A→ (ii) H3O+(i) NaOHB→ (ii) H2SO4,Δ (i EtOHCA \xrightarrow[\text { (ii) } \mathrm{H}_{3} \mathrm{O}^{+}]{\text {(i) } \mathrm{NaOH}} \mathrm{B} \xrightarrow[\text { (ii) } \mathrm{H}_{2} \mathrm{SO}_{4}, \Delta]{\text { (i } \mathrm{EtOH}} \mathrm{C}

' A ' shows positive Lassaigne's test for N and its molar mass is 121.

'B' gives effervescence with aq NaHCO3\mathrm{NaHCO}_{3}

'C' gives fruity smell

Identify A,B\mathrm{A}, \mathrm{B} and C from the following

  1. Option A:
    Option A figure
  2. Option B:
    Option B figure
  3. Option C:
    Option C figure
  4. Option D:
    Option D figure
    Correct

Answer: D

Step-by-step solution

Compound (A) is likely to be amide which gives carboxylic acid (B) after hydrolysis.

Compound (B) reacts with alcohol to give ester  (i) CONHNaOH2⏟(ii) H3O+\underbrace{\stackrel{\mathrm{CONH}}{\text { (i) }} \mathrm{NaOH}_{2}}_{\text {(ii) } \mathrm{H}_{3} \mathrm{O}^{+}}
