(a) Interpretation: The given compound is to be classified as aromatic, antiaromatic or not aromatic. 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.
