The observation that cycloheptatrienone is stable but cyclopentadienone is so reactive and cannot be isolated is to be explained taking into account the polarity of the carbonyl group. Concept introduction: Carbonyl group is polar as oxygen is more electronegative than carbon. According to Huckel’s rule, any specie that is cyclic, planar and has (4n+2) delocalized Ï€ electrons will be aromatic and stable. Thus species with 2, 6, 10, 14 etc. Ï€ electrons will be aromatic and stable. To explain: The observation that cycloheptatrienone is stable but cyclopentadienone is so reactive and cannot be isolated is taking into account the polarity of the carbonyl group.

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.
