Rationalise the statement and give reaction :
Lead (IV) chloride is highly unstable towards heat.

Text Solution

Verified by Experts

Due to inert pair effect, the +2 oxidation state of lead is more stable than +4 oxidation state. Thus, `PbCl_4` on heating decomposes to form `PbCl_2`.
`PbCl_4 overset(Delta)to PbCl_2 + Cl_2`
