The species formed when each of the given processes applied to cyclooctatetraene is aromatic or not is to be predicted. Concept introduction: Huckel’s rule is used to determine the aromatic character of a compound. Huckel’s rule states that, for a species to be aromatic, the number of π electrons in must be equal to 4n+2 , where n is an integer, the continuous delocalization of electrons must be there and the compound must be planar.

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.
