Q22 / 155 · WBJEE 2025 · Chemistry

Increasing order of the nucleophilic substitution of following compounds is Figure

  • A
    $I \lt I I I \lt I I \lt I V$
  • Correct answer
    B
    $I I \lt I \lt I I I \lt I V$
  • C
    $I I \lt I I I \lt I \lt I V$
  • D
    $I V \lt I I I \lt I I \lt I$

Solution

$I I \lt I \lt I I I \lt I V$ Electron withdrawing group decreases the electrondensity and favours nucleophilic substitution.

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