The mechanism for the synthesis of the given compound frommethyl vinyl ketone and diethyl malonate is to be proposed. Concept Introduction: > A molecule that consists of a ketone group on the β- carbon atom of an ester is generally known as β- keto ester. > β- keto ester contains an active methylene group between two carbonyl groups in its structure. Diethyl malonate is an example of β- keto ester. > The carbanion acts as nucleophile while it undergoes addition reaction to α,β- unsaturated carbonyl compound, such reaction is known as Michael addition reaction.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
