How can the following conversion be effected?
Nitrobenzene `to` Azoxybenzene.

Explanation

When nitrobenzene is subjected to reduction with glucose and NaOH forms the intemediate products nitrosobenzene and phenyl hydroxyl amine. These undergo bimolecular condensation reaction to give azoxy benzene.
`{:(C_6H_5NO_2overset(" Glucose+NaOH ")to C_6H_5NOunderset(-H_2O)overset(triangle)(to)C_6H_5-N=N-C_6H_5),(" Nitrosobenzene Azoxy benzene"):}`.
