The reason corresponding to the fact that the given compound has significant dipole, even though it is composed of only C − C and C − H bonds, is to be explained. The direction of dipole is to be illustrated in the given molecule using resonance structures. More electron rich ring is to be identified. Concept introduction: A molecule must be cyclic, planar, completely conjugated and should follow Huckel’s rule to be classified as aromatic . For an antiaromatic molecule, the molecule must be cyclic, planar, completely conjugated and have 4 n π electrons. For a non-aromatic molecule, the molecule lacks the one of the requirements to be aromatic or anti aromatic molecule. According to the Huckel’s rule the number of π electrons in the molecule must be equal to ( 4 n + 2 ) .

Question

Definition Definition Rule that estimates whether a given organic planar ring structure will show an aromatic property. A cyclic ring molecule is said to follow Hückel’s rule if the л-electrons count in a molecule is [4n+2], where n stands for a positive numerical value. It is also called the [4n+2] rule. Hückel's rule, sometimes referred to as the aromaticity rule, is one but not the only criteria to judge a molecule for aromaticity.
