$PbI_4$

Vedclass · Answer

(D) Group-$14$ elements form halides of the formula $MX_2$ and $MX_4$ (where $X = F, Cl, Br, I$).$PbI_4$ does not exist because lead $(Pb)$ is a heavy element and exhibits an inert pair effect.The energy released during the formation of the $Pb-I$ bonds is not sufficient to promote an electron from the $6s$ orbital to the $6p$ orbital to achieve the $sp^3$ hybridization required for tetrahalide formation.Consequently,$Pb$ prefers to exist in the $+2$ oxidation state rather than the $+4$ oxidation state when bonded to large,less electronegative atoms like iodine.
