(a)
Interpretation: The starting material required for the preparation of given imine is to be determined.
Concept introduction:
(b)
Interpretation: The starting material required for the preparation of given imine is to be determined.
Concept introduction: Aldehyde or ketone on reaction with primary amine forms imine. Imine is also known as Schiff base. The nucleophilic attack of primary amine on carbonyl carbon results in the formation of intermediate carbinolamine. This intermediate loses water to form an imine.
