Compund `(A)C_(8)H_(9)` Br 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 anhydride on heating Identify the compound (A) .

Options

A.
B.
C.
D.

Answer

D

Explanation

Compound A gives a precipitate with alcoholic `AgNO_(3)` (here white is misprinting because the colour of ppt is light yellow so it must contains Br in side chain On oxidation it gives `C_(6)H_(6)O_(4)` which shown the presence of two alkyl chains attached directly with the benzene nucleus Since compund `B` gives anhydride on heating the two alkyl substituent must oC Cupy adjacent (1,2) position Thus A must be and the reactions are as follows
