The explanations of the stability of the compounds, cyclopropenone and cycloheptatrienone and the instability of the compound cyclopentadienone are to be stated. Concept introduction: Huckel’s rule of the organic chemistry states that a monocyclic system will be aromatic only if there are ( 4 n + 2 ) pi electrons in the structure. The number of carbon atoms in the cyclic system is irrelevant to the aromaticity of the molecule. It is based on the number of delocalised electrons present.

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.
