Answer» SOLUTION :(i) An organic compound (A) `C_(7)H_(8)`, on oxidation at 773 K in the presence of `V_(2)O_(5)` gives compound (B) of molecular formula `C_(7)H_(6)O`. (ii) (B) reduces Tollen's reagent. (B) on heating with sodium acetate in the presence of acetic ANHYDRIDE gives `(C_(9)H_(8)O_(2))`(C). `underset((A))(C_(6)H_(5)-CH_(3))underset(V_(2)O_(5)//773K)OVERSET((O))toC_(6)H_(5)-CHO+H_(2)O` `underset((B))(C_(6)H_(5)-CHO)+CH_(3)-CO-O-CO-CH_(3)overset(CH_(3)COONa)tounderset((C))(C_(6)H_(5)-CH=CH-COOH)`
