(a)
Interpretation:
In the given ester, the portion that came from the acid is to be circled. The ester linkage is to be pointed out.
Concept introduction:
Esters are organic compounds which are formed from acids in which one hydroxyl group is replaced by an alkoxy group. Esters are formed by the reaction between a carboxylic group and an alcohol under the presence of a catalyst which supplies a proton.
