Q34 / 160 · WBJEE 2015 · Chemistry

The total number of aromatic species generated in the following reactions is

A
zero
B
2
Correct answer
C
3
D
4

Solution

Criteria for aromaticity (Huckel rule) The cyclic $\pi$ molecular orbital (electron cloud) formed by overlap of $p$ -orbitals must contalu $(4 n+2) \pi$ -electrons, where $n=$ integer 0,1,2,3 Pte. This is known as Huckel rule.

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