Question

What happens when PCI, is heated?​

Answer 1

Answer:

The vapour density of PCI, is 104.25 but when heated to 230°C, its vapour density is reduced to 62. The degree of dissociation of PCI, at this temperature will be 6.8% d) 64% b) 68% c) 46%

Answer 2

It has three equatorial and two axial bonds. The equatorial bonds are stronger than the axial ones. Therefore, when PCl5 is heated strongly, it decomposes to form PCl3.
