(a) Interpretation: The carbonyl compound and amine or alcohol needed to prepare the given compound are to be predicted. Concept introduction: A carbonyl compound ( aldehyde or ketone ) reacts with 1 ο amine to yield imine, and reacts with 2 ο amine to yield enamine. The mechanism of both reactions are identical except for the last step. The last step for enamine formation involves loss of a proton from the adjacent C − H bond, whereas the last step for imine formation involves loss of a proton from the N atom itself.

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.
