Answer #1

1. NH3 use sp3 hybrid orbitals. The bonds in NH3 are made from the overlap of three sp3 hybrid orbitals on the nitrogen.

2. H2N-NH2 use sp3 hybrid orbitals.It has 4 e- pairs around each N, and is trigonal pyramidal, so its a sp3 hybridisation .

3. NO3- use sp2 hybrid orbitals.It has three electron pairs (i.e. sigma bonds) which determine the geometry and one delocalized pi bond, therefore it is trigonal planar, and has sp2 hybridization.
