Out of the given imines, which is more reactive and which is least reactive is to be determined. Concept introduction: Aldehydes are more reactive than ketones because ketones are stabilized more by inductive effects. The alkyl groups are electron donating, so they decrease the concentration of positive charge at the carbonyl carbon. With less concentration of positive charge at that carbon, the carbonyl group is less susceptible to attack by a nucleophile bearing excess negative charge.

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.
