Account for the following: The +2 oxidation state of lead is more stable than +2 oxidation state of Tin.

Text Solution

Verified by Experts

Elements of groups 14 are C, Si, Ge, Sn and Pb: These elements show oxidation states of +2 and +4. Due to inert pair effect, the stability of lower oxidation state increases as we more down the group. Therefore, +2 oxidation state of Pb is more stable than its `P_(+4)` oxidation state.
