JEE Main Chemistry Question (2026) — Solution

Question

Increasing order of electron withdrawing power of following functional groups is: a. -CN b. -COOH c. -NO_2 d. -I

Options

  1. A. c < b < d < a
  2. B. c < a < b < d
  3. C. d < b < a < c
  4. D. a < b < c < d

Answer

C. d < b < a < c

Step-by-step solution

The electron withdrawing power (-I effect) of various functional groups follows the standard experimental order: -NO_2 > -CN > -COOH > -F > -Cl > -Br > -I Based on this series, the increasing order of electron withdrawing power for the given groups is: -I This corresponds to the sequence d Answer: d < b < a < c
