(a) Interpretation: The carboxylic acid cannot be prepared by the malonic ester synthesis is to be explained. Concept introduction: The α hydrogen attached to the diester is acidic in nature and on heating diester followed by hydrolysis gives β- diacid which loses CO 2 to give carboxylic acid. The formed acid has components of both alkyl halide and malonic ester.
