The skeletal structure of the molecule given is to be drawn. How it can be prepared from a ketone and an amine is also to be shown. Concept introduction: Secondary amines react with aldehydes and ketones to yield enamines, R 2 NCR=CR 2 . The reaction is a typical example of nucleophilic addition reaction in which water is eliminated from the intermediate initially formed leading to the formation of a new C=Nu double bond. To draw: The skeletal structure of the molecule given. To show: How it can be prepared from a ketone and an amine.

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.
