Q. A compound $(A)$ (molecular formula $–C_{8}H_{8}O$) on treatment with $NH_{2}OH \bullet HCl$ gives $B$ and $C$ rearrange to give $D$ and $E$ respective 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 the 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 $A$
