Compound that is not aromatic has to be identified among the given structures. Concept Introduction: Huckel’s rule states that based on the number of pi electrons planar, monocyclic, and conjugated polyene compounds can be classified as aromatic or anti-aromatic. a) The number of π electrons in a cyclic conjugated system is 4 n where n is an integer, then it is antiaromatic. b) The number of π electrons in a cyclic conjugated system is ( 4 n + 2 ) where n is an integer, and then it is aromatic.

Answer 1

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.
