The information regarding the structure of chlorophyll is given. Circling of the double bond in the large cyclic pi conjugated system that makes it aromatic and pi electrons in this aromatic system are to be stated. Concept introduction: The conditions that a molecule must follow to be aromatic are shown below. The given compound must be cyclic in nature. It must be planar. There must be no sp 3 hybridized carbon in the given compound. The compound must follow Huckel’s rule of aromaticity that is ( 4 n + 2 ) π electron system must be present. If the given compound follows first three conditions but it follows 4 n π electron system, then it is antiaromatic in nature. If the given compound fails to follow any of the above conditions then it is non-aromatic in nature.

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.
