Question

In which of the following processes nitrogen is reduced?
(a). NO2-→NO3- (b) NO2- → NO2- (c) NO2 -→ NO3-
(d) NH4+ → N2​

Answer 1

Explanation:

In fact, there is sp3 hybridization on each nitrogen. Considering the lone pair of electrons also one bond equivalent and with VSEPR Theory adapted, the NH2 and the lone pair on each nitrogen atom of the N2H4 molecule assume staggered conformation with each of H2N-N and N-NH2 segments existing in a pyramidal structure.
