Q. Nitrobenzene is reduced by Zn and alcoholic potash mixture to get
A) $C_{6}H_{5} - NH_{2}$
B) $C_{6}H_{5} - NH - NH - C_{6}H_{5}$
C) $C_{6}H_{5} - N - N - C_{6}H_{5}$
D) $C_{6}H_{5} - NH - CO - C_{6}H_{5}$
Explanation
(b)
Nitrobenzene is reduced by Zn and alcoholic KOH into hydrazobenzene.
$2C_{6}H_{5}NO_{2} + 10H\overset{Zn + alc.KOH}{\rightarrow}C_{6}H_{5} - NH - NH - C_{6}H_{5} + H_{2}O$
hydrazobenzene
