The reason corresponding to the fact that C = C of an enol is more nucleophilic than C = C of an alkene is to be stated. Concept Introduction: The isomers which have same molecular formula but different connectivity of atoms are constitutional isomers. The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. The nucleophilic reaction that consists of bimolecular as well as bond-making and bond-breaking steps is termed as S N 2 reactions. This is a one-step reaction in which both nucleophile and substrate participate in the rate determining step. The chemical equilibrium that exists between a keto form of a compound and an enol form of the same compound is known as keto-enol tautomerism. Tautomers refer to these keto and enol forms.

Question

Explain why the C=C of an enol is more nucleophilic than the C=C of an alkene, despite the fact that the electronegative oxygen atom of the enol inductively withdraws electron density from the carbon–carbon double bond.
