[Group number of central atom –Valency of the central atom].
For ions : No. of electron pairs = No. of atoms bonded

To determine the hybridization of an atom in a molecule/ion, we need to consider the number of regions of electron density around the atom. Each bond and lone pair of electrons counts as one region of electron density.
Let's analyze each molecule/ion:
1. BF3:
- B has 3 regions of electron density (3 bonds with F atoms).
- According to the VSEPR theory, BF3 has a trigonal planar geometry.
- In a trigonal planar geometry, the central atom is sp2 hybridized.
2. NO2-:
- N has 3 regions of electron density (2 bonds with O atoms and 1 lone pair).
- According to the VSEPR theory, NO2- has a bent or angular geometry.
- In a bent or angular geometry, the central atom is sp2 hybridized.
3. NH2-:
- N has 3 regions of electron density (2 bonds with H atoms and 1 lone pair).
- According to the VSEPR theory, NH2- has a bent or angular geometry.
- In a bent or angular geometry, the central atom is sp2 hybridized.
4. H2O:
- O has 4 regions of electron density (2 bonds with H atoms and 2 lone pairs).
- According to the VSEPR theory, H2O has a bent or angular geometry.
- In a bent or angular geometry, the central atom is sp2 hybridized.
Based on the analysis above, we can conclude that the central atom is sp2 hybridized in the molecules/ions BF3 and NO2-. Therefore, the correct answer is option 'C'.
