Increasing order of electron withdrawing power of following functional groups is: a. -CN b. -COOH c. -NO₂ d. -I
Options
- Ac < b < d < a
- Bc < a < b < d
- Cd < b < a < c
- Da < b < c < d
Correct 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: -NO₂ > -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
