Options

  1. ANaOH / H^ + reacts with
  2. BNaOH / H^ + reacts with
  3. CCH3CHO\mathrm{CH}_3 \mathrm{CHO}
  4. DHCHO

Correct answer

C. CH3CHO\mathrm{CH}_3 \mathrm{CHO}

Step-by-step solution

The aldehyde/ketone, those do not contain α\alpha-H atom; show Cannizzaro reaction. In CH3CHO\mathrm{CH}_3 \mathrm{CHO}, carbonyl group is attached to C-atom having α−H\alpha-\mathrm{H}; Hence, CH3CHO\mathrm{CH}_3 \mathrm{CHO} do not show Cannizzaro reaction.
