Question

The stability of MCl4 decreases from CCl4 to PbCl4.
Why? ​

Answer 1

Answer:

CCl14 is a stable whereas PbC14 is of Powerful oxidising agent. By the term inert-pair effect is often used in relation to the increasing stability of oxidation states that are two less than the group valency for the heavier elements of groups.Due to the inert pair affect the stability of the +2 state increases on moving down the group from carbon to lead.Due to this affect the stability of the +2 state increases on moving down the group from carbon to lead.
