The pi-electron energies of a cyclic and an open-chain compound are to be explained. Concept introduction: A cyclic molecule containing a 4n π -electron system, not following Huckel’s rule ( 4 n + 2 ) , is known as an antiaromatic molecule. A cyclic molecule containing a π -electron system, following Huckel’s rule ( 4 n + 2 ) , is known as an aromatic molecule.

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.
