Vedclass · Answer

(B) The reaction between a ketone (like cyclohexanone) and a secondary amine (like dimethylamine) in the presence of an acid catalyst results in the formation of an enamine.The reaction involves the nucleophilic attack of the secondary amine on the carbonyl carbon,followed by the loss of a water molecule to form a carbon-carbon double bond adjacent to the nitrogen atom.The product formed is $N,N$-dimethylcyclohex$-1-$en$-1-$amine,which is classified as an enamine.Therefore,the correct option is $B$.

The reaction of cyclohexanone with dimethylamine in the presence of a catalytic amount of an acid forms a compound if water is continuously removed during the reaction. The compound formed is generally known as:
