(b) It is a test for acetate radical.

(c) CH₃COOC₂H₅ $\stackrel{\mathrm{HOH}}{\to }$CH₃COOH+C₂H₅OH

The Reformatsky reaction is a method for the preparation of β-hydroxy esters. It involves the reaction of an α-halo ester with a ketone or aldehyde in the presence of zinc metal, which forms a zinc enolate intermediate that reacts with the carbonyl compound to give the β-hydroxy ester product.

(b) Caproic acid is ${\mathrm{CH}}_3({\mathrm{CH}}_2{)}_4\mathrm{COOH}.$

(b) Lactic acid prepared from meat extract of muscles is dextro-rotatory and is therefore called sarcolactic acid 

(a) Resonance in carboxylate ions give rise to identical bond lengths.

(c) 2HgCl2 + HCOOH  ----->  Hg2Cl2  + 2HCl +CO2

(c) ${\mathrm{CH}}_2={\mathrm{CH}}_2 + {\mathrm{PdCl}}_2 + {\mathrm{H}}_2\mathrm{O} \stackrel{{\mathrm{CuCl}}_2}{\to }{\mathrm{CH}}_3\mathrm{CHO} + \mathrm{Pd} + 2\mathrm{HCl}$;

This is Wacker method.
