Why PbCl4 is unstable than PbCl2?

${ \large {\underline{ \blue{ \sf{Answer:}}}}}$

This is due to inert pair effect. Pb has four electrons in its outermost shell,two are in s orbital & two in the p orbital. ... The s electrons are inert & are not that easily removed to give the group valency of 4.
