Compound (A) C_(8)H_(9)Br, gives a light yellow precipitate when warme

1.	Compound (A) C_(8)H_(9)Br, gives a light yellow precipitate when warmed with alcoholic AgNO_(3) (B) easily form anhydride on heating. Identify the compound (A)
Answer» Solution :Since COMPOUND (A), `MF C_(8)H_(9)Br` gives a light yellow ppt. when warmed with alcoholic `AgNO_(3), Br` must be PRESENT in the side chain. The option (B) is ruled out because Br is present in the ring. Again oxidation of (A) gives an acid B. `C_(8)H_(6)O_(4)` which readily form an anhydride on heating, hence compound (A) must be `o-`disubstituted out of the remaining three option (A, B, C) only (A) is di-substituted `:.` option A is true
