Compound (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 forms anhydride on heating Identify the compound (A)

Options

A.
B.
C.
D.

Answer

D

Explanation

Compound A gives a precipitate with alcoholic `AgNO_(3)`, so it must contain Br in side chain. On oxidation, it gives `C_(8)H_(6)O_(4)`, which shows the presence of two alkyl chains attached directly with the benzene nucleus.
Since, compound B gives anhydride on heating therefore, the two alkyl substituent must occupy adjacent (1, 2) position.
