Step-by-step solution

Compound (A), C _ 8 H _ 9 Cl , gives a white precipitate when warmed with alcoholic AgNO _ 3 . Oxidation of (A) gives

Compound (A) gives a white precipitate when warmed with alcoholic AgNO3{AgNO}_{3}means it contain a removable chloride atom(Benzylic position). Oxidation of (A) gives an acid (B), C8H6O4{C}_{8}{H}_{6}{O}_{4}. (B) easily forms anhydride on heating. Means both acid should be ortho position of each other.
