In organic chemistry, Hückel's rule predicts that a planar ring molecule will have aromatic properties if it has 4n + 2 π electrons, where n is a non-negative integer. The quantum mechanical basis for its formulation was first worked out by physical chemist Erich Hückel in 1931. The succinct expression as the 4n + 2 rule has been attributed to W. v. E.

It has six delocalised ir electrons. 4n + 2 = 6 4n = 6 – 2 4n = 4 n = 1, obeys Huckel’s rule with n = 1 (b) 1. Molecule is non-planar. Hence it is a non-aromatic compound. (c) It has a co-planar structure. It has two delocalised it electrons. 4n + 2 = 2 4n = 0 n = 0 Hence is an aromatic compound. buy sheets of plastic
