The radical is aromatic because it has

A

7 p-orbitals and seven unpaired electrons

B

6 p-orbitals and 7 unpaired electrons

C

6 p-orbitals and 6 unpaired electrons

D

7 p-orbitals and 7 unpaired electrons

Text Solution

Verified by Experts

The correct Answer is:
C

6 p-orbitals and 6 unpaired electrons form a cyclic electron cloud containing 6 `pi`, i.e., (4 n +2) `pi`-electons which is responsible for aromatic character. The seventh electron as such has nothing to do with the aromatic character of benzyl radical.
