### 2F:7.d

Identify the hybrid orbitals used by the atom in boldface red type in each of the following species:
d. SeF3+

Thanks

SeF3+ has 4 regions of electron density because of its lone pair and 3 bonded atoms, so its steric number is 4, giving it a hybridization of sp3.

### Re: 2F:7.d

The number of hybridized orbitals is equal to the number of atomic orbitals around the central atom. So, the hybridization is sp3 to match the four atomic orbitals around the central atom that is seen in its Lewis structure.
