Compound (A) `(C_(8)H_(8)O)` on treatment with `NH_(2)OH.HCl` gives (B) and (C ). (B) and (C ) rearrange to give (D) and E, respectively, on treatment with acid. (B), (C ), (D), and (E ) are all isomers of molecular formula `(C_(8)H_(9)NO)`. When (D) is boiled with alcoholic KOH, an oil (F) `(C_(6)H_(7)N)` separates out. (F) reacts rapidly with `CH_(3)COCl` to give back (D). On the other hand, (E ) on boiling with alkali followed by acidification gives a white solid (G) `(C_(7)H_(6)O_(2))`. Identify (A) to (G).

Answer

`underset("Acetophenone")((A))underset("Acetophenone oxime")((B)) underset("Z-Acetophenone oxime")((C))`
`C_(6)H_(5)-NH-overset(O)overset(||)C-CH_(3) C_(6)H_(5)-overset(O)overset(||)C-NH-CH_(3) C_(6)H_(5)-NH_(2) C_(6)H_(5)-COOH`
`underset("Acetanilide")((D))underset("N-methyl benzamide")((E))underset("Aniline")((F))underset("Benzoic acid")((G))`
