Options

  1. AI > III > II
  2. BII > III > I
  3. CII > I > III
  4. DIII > I > II

Correct answer

B. II > III > I

Step-by-step solution

Aromatic aldehydes and ketones are less reactive than the corresponding aliphatic analogues towards nucleophilic addition reactions due to the +R effect of benzene ring. Further, aldehydes are more reactive than ketones due to +I effect and steric effect of alkyl group. Therefore, the ease of nucleophilic addition will follow the order
