Question

Which of the following groups is electron-withdrawing by induction (-I) but electron-donating by resonance (+M)?
Options
A -NO2
B -CN
C -Cl
Correct Answer
D -CH3
Correct Answer

Option C is the correct answer.

Detailed Explanation

Halogens (Cl, F, Br) are electron-withdrawing by induction (-I) due to high electronegativity but electron-donating by resonance (+M) due to lone pairs that can delocalize into pi systems.

Hint

Lone pairs on halogen can participate in resonance.
