Q. Aromatic compound among other things should have a $\pi$-electron cloud containing $(4n + 2)\pi$ electrons where, $n$ cannot be
A) $\frac{1}{2}$
B) 3
C) 2
D) 1
Explanation
(a)
According to Huckel’s rule, an aromatic compound should have $(4n + 2)\pi$-electrons. Where, $n$ is an integer, $i.e.,$ 0, 1, 3, 4, … and possesses unusual stability due to the delocalisation of $\pi$-electrons.
