Question

What is formed when nitrobenzene is reduced using zinc and alkali?

• A. Phenol
• B. Hydrazobenzene
• C. Aniline
• D. Nitrosobenzene

Answer 1

Answer: (B)

Reduction of nitrobenzene

Medium	Reagent	Product
Acid	$Sn/HCl$	Aniline
Neutral	$Zn/N{H}_{4}Cl$	N - phenylhydroxyl amine
Alkaline	$N{a}_{3}As{O}_3/NaOH$	Azoxy benzene
	$Zn/NaOH,C{H}_{3}OH$	Azo benzene
	$Zn/NaOH,C_2{H}_{5}OH$	Hydrazo benzene
Metallic hydride	$LiAl{H}_4$	Aniline
Electrolytic reduction	dil. $H_{2}S{O}_4$	Aniline

When nitrobenzene is reduced by zinc and alkali then hydrazobenzene is formed.
