(a) Interpretation: The enamine product obtained after the reaction of acetone and piperidine is to be drawn. Concept introduction: When aldehydes or ketones react with a secondary amine , formation of enamine takes place. The nitrogen analog of an enol is known as enamine. The nucleophilic addition reaction of the secondary amine to the carbonyl carbon atom results in the formation of hemiaminal intermediate which further on dehydration forms the enamine product.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
