Solution:
Redistribution of the energy of orbitals of individual atoms to give orbital of equivalent energy happens when two atomic orbitals combine to form hybrid orbital in a molecule. This process is called hybridization.
Ions Hybridization $NO_{2}^{-}$ $sp^{2}$ $NO_{3}^{-}$ $sp^{2}$ $NH_{2}^{-}$ $sp^{3}$ $NH_{4}^{+}$ $sp^{3}$ $SCN^{-}$ sp
| Ions | Hybridization |
|---|---|
| $NO_{2}^{-}$ | $sp^{2}$ |
| $NO_{3}^{-}$ | $sp^{2}$ |
| $NH_{2}^{-}$ | $sp^{3}$ |
| $NH_{4}^{+}$ | $sp^{3}$ |
| $SCN^{-}$ | sp |
