An explanation for A as aromatic and B as not aromatic is to be stated. Concept introduction: An aromatic compound is planar, cyclic, conjugated, and contains 4 n + 2 π electrons. An antiaromatic compound is planar, cyclic, conjugated, and contains 4 n π electrons. A nonaromatic compound lacks one of the four requirements to be an aromatic or antiaromatic.

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.
