Rationalise the statement and give reaction :
Lead is known not to form an iodide, `PbI_4`.

Text Solution

Verified by Experts

`PbI_4` does not exist because the amount of energy released by the initially formed two Pb-I bonds is not sufficient enough to unpair the `6s^2` electrons and promote one of them to the higher energy 6p orbital. The strong oxidising power of `Pb^(4+)` ion and strong reducing power of `I^(-)` ion is also responsible for the non-existence of `PbI_4`.
