### 2F.9

Identify the hybrid orbitals used by the phosphorus atom in each of the following species: (a) PCl41; (b) PCl62; (c) PCl5; (d) PCl3.

### Re: 2F.9

Basically in order to determine the hybridization, you need to find how many regions of electron density there are. Once you figure that out by determining molecular shape, you match the corresponding hybridization to it. For example, for PCl4+, it has 4 regions of electron density (from its tetrahedral shape), so the hybridization would be sp3 (one s + three p = 4 total).
