For the following compounds, (2) C ₆ H ₅- CHO (3) p- CH ₃- C ₆ H ₄- CHO (4) p- CH ₃ O - C ₆ H ₄- CHO The correct order for nucleophilic addition reaction is

Options

  1. A2>1>3>4
  2. B4>3>2>1
  3. C2>3>4>1
  4. D4>2>3>1

Correct answer

C. 2>3>4>1

Step-by-step solution

For the nucleophilic addition reaction to be faster, the carbonyl C-atom should be more electrophilic thus, the correct order is C ₆ H ₅- CHO >p- CH ₃- C ₆ H ₄- CHO
