(a)
Interpretation:
The given substituted acetic acid has to be prepared using malonic ester synthesis.
Concept Introduction:
Malonic ester is a versatile starting material for the formation of new carbon-carbon bonds. It is because of the presence of acidic α-hydrogens between two carbonyl groups, the nucleophilicity of the enolate anion formed by the loss of α-hydrogen and the ability of the product to undergo decarboxylation after hydrolysis of ester.
