Using IIuckel's rule, show that cyclopentadienyl anion and naphthalene is aromatic.

Text Solution

Verified by Experts

In cyclopentadienyl anion, 6 `pi` electrons
`therefore` n = 1, In Huckel's rule
`(4n + 2)pi = (4 xx 1 + 2)pi = 6pi` electrons.
It is an aromatic because it obeys Huckel's rule and other rule.
(b) In naphthalene 10`pi` electrons

n = 2
`therefore (4n + 2)pi = (4 xx 2 + 2)pi = 10 pi ` electrons.
It is an aromatic because it obeys Huckel rule and other rule.
