Hydrazobenzene can be obtained by reducing nitrobenzene with:
Correct answer: D. Zn + NaOH
- A. Sn + HCl
- B. Zn + NH4Cl
- C. Na3AsO3 + NaOH
- D. Zn + NaOH
Explanation
When nitro compounds are reduced, then amines are formed. The bulky nitrobenzene is reduced using zinc, and sodium hydroxide. The reaction is such that 2 moles of nitrobenzene are involved along with 10 hydrogen atoms, for reduction, with Zn in alkaline medium (NaOH). The reaction results in forming a compound with 2 benzene rings and secondary amines. This compound is called as hydrazobenzene.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
