To determine the number of hybrid orbitals in a molecular compound, look at the central atom's regions of electron density. The number of regions of electron density is the number of hybrid orbitals for that atom.

Hybrid Orbitals:
2e- pairs = sp
3e- pairs = sp^2
4e- pairs = sp^3
5e- pairs = sp^3d
6e- pairs = sp^3d^2

It is helpful to draw the lewis structure of the compound you are working with. Then, for each atom, count the number of electron pairs that it has. Once you have these numbers, then you can utilize the information above to figure out the hybridization that corresponds with the number of electron pairs.
