`PbCl_(4)` exists but `PbBr_(4)` and `PbI_(4)` do not because ofA. bromine and iodine are more electronegative these chlorine.B. iodine and bromine are smaller in size.C. larger iodine and bromine are able to reduce `Pb^(4+)` to `Pb^(2+)` or `Pb`.D. the statement is incorrect

Answer» Correct Answer - C
`Pb^(4+)` has higher polarising power and `Br^(-)` and `I^(-)` being larger in size can easily give the electrons to `Pb^(4+)`, i.e. as compared to `Cl^(-),Br^(-)` and `I^(-)` are good reducing agents.
