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.

(a)

Interpretation:

Total number of Π electrons present in a polycyclic hydrocarbon coronene is to be determined.

Concept introduction:

Each C=C double bond consists of two Π electrons.

Interpretation Introduction

(b)

Interpretation:

It is to be explained whether the number of Π electrons in the given compound is consistent with the fact that the compound is aromatic.

Concept introduction:

A molecule, to be aromatic, must obey Huckel’s rule (4n+2)π electrons. Huckel’s rule for aromaticity states that if a species possesses a pi system of molecular orbitals constructed from p-orbitals that are fully conjugated around a ring (sp2 hybridized), then the species is:

Aromatic, if the number of electrons in that π- system is 2,6,10,14,1,and so on.

Antiaromatic if the number of electrons in that π- system is 4,8,12,16,20,and so on.
