The expected products of the given acid catalysed reaction are to be stated. Concept introduction: When aldehydes or ketones react with a primary amine , formation of a carbinolamine takes place. Then, dehydration takes place to give C = N double bond of an imine. Imine formation takes place in the presence of an acid or a base. This reaction is reversible and it is accompanied by loss of water molecule.

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.
