Criteria for Huckel’s rule:

(i) Planarity-The molecule must be planar.

(ii) Complete delocalisation of π electrons

(iii) Presence of (4n + 2)π electrons in ring where n is an integer (n = 0, 1, 2, …). If the molecule has a number of π electrons that satisfies this rule, then it is considered to be aromatic. If the number of π electrons does not satisfy this rule, then the molecule is considered to be non-aromatic.

The compounds which follow Huckel’s rule are:
