For the given cation, using Frost circle an energy diagram should be drawn and it should be predicted whether this cation exhibit aromatic stabilization or not Concept introduction: The conditions for aromatic compound are, 1. It should be planar 2. It must obey the Huckel’s rule The requirement of an odd number of electron pair is called Huckel’s rule . A compound can only be aromatic if the number of π electron in the ring is 2, 6,10,14,18 and so on. This series of number can be expressed mathematically as 4n+2 , where n should be an integer and the compound is aromatic. 3. Continuous conjugated π system(all carbon should be in sp 2 hybridized state) If any compound which doesn’t satisfy one of the above condition then the compound is not aromatic A five membered ring will be aromatic if it contains six π electrons. In order to have six π electrons, one of the carbon atoms must possess two electrons. It should be a carbanion. A Frost circle is used to draw an energy diagram showing the relative energy levels of the molecular orbitals associated with ring comprised of a continuous conjugated π system

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.

Interpretation: For the given cation, using Frost circle an energy diagram should be drawn and it should be predicted whether this cation exhibit aromatic stabilization or not

Concept introduction:

The conditions for aromatic compound are,

2. It must obey the Huckel’s rule

The requirement of an odd number of electron pair is called Huckel’s rule. A compound can only be aromatic if the number of π electron in the ring is 2, 6,10,14,18 and so on. This series of number can be expressed mathematically as 4n+2 , where n should be an integer and the compound is aromatic.

3. Continuous conjugated π system(all carbon should be in sp2 hybridized state)

If any compound which doesn’t satisfy one of the above condition then the compound is not aromatic

A five membered ring will be aromatic if it contains six π electrons. In order to have six π electrons, one of the carbon atoms must possess two electrons. It should be a carbanion.
