Phosphorus halides

There are two types of phosphorus halides, PX ₃ and PX ₅
.

At room temperature, PX ₃ is a covalent compound, PF ₅ is a covalent compound, and PCI ₅ and PBr ₅ are ionic compounds

PF ₃ is a colorless gas, PCl ₃ and PBr ₃ are colorless liquids, and PI ₃ is a red solid
.

The PF _{.

Phosphorus trihalide is prone to hydrolysis reaction and alcoholysis reaction, and is also easy to be oxidized
.

The PCI ₃ hydrolysis reaction is very thorough, and the hydrolysis cannot be inhibited even in concentrated hydrochloric acid
.
Phosphorus pentahalide is easier to hydrolyze, such as
2.

Phosphorus sulfide
There are many phosphorus sulfides, all based on P ₄ tetrahedron, as shown in Figure 12-14
