a) CH3CH2CONHCH3
Interpretation:
To prepare the given amides by using an acid chloride and an
Concept introduction:
Evidently, in deciding the starting materials (reagents) for the synthesis, we observe that there are two distinct parts of the amide viz the acyl part which should come from the respective acyl chloride viz propanoyl chloride; and the amine part , which should come from the oppropriate amine methylamine.
b) N,N-Diethylbenzamide
Interpretation:
To prepare the given amides by using an acid chloride and an amine or ammonia.
Concept introduction:
Evidently, introspection of the target molecule viz the amide, shows that it has two distinct parts, viz the acyl part, Phco should come from the acid chloride, viz benzoyl chloride, and the amine part should come from the appropriate amine, in this case it is N,N-diethyl amine.
c) Propanamide
Interpretation:
To prepare the given amides by using an acid chloride and an amine or ammonia.
Concept introduction:
Introspection of the target amide shows that there are two distinct parts viz, the acyl part and the amine part the acyl part should come from the appropriate acid chloride in this case, it is propanoyl chloride while the amine part should be provided from ammonia.
