Compound (A), C 8 H 9 Cl , gives a white precipitate when warmed with alcoholic AgNO 3 . Oxidation of (A) gives an acid (B), C 8 H 6 O 4 . (B) easily forms anhydride on heating. Identify the compound (A).

Step-by-step solution

Compound (A) gives a white precipitate when warmed with alcoholic AgNO 3 means it contain a removable chloride atom(Benzylic position) . Oxidation of (A) gives an acid (B), C 8 H 6 O 4 . (B) easily forms anhydride on heating. Means both acid should be ortho position of each other.
