(a)
Interpretation:
To propose a mechanism for the formation of succinic anhydride in the presence of acetic anhydride and how acetic anhydride makes it easier to form the succinic anhydride.
Concept introduction:
Succinic anhydride is a type of cyclic anhydride formed by the dehydration of dicarboxylic acid that is succinic acid. The cyclic anhydride is formed easily in the presence of anhydride such as acetic anhydride.
The reaction is:
