Which Of The Following Is The Least Stable And Its Chemistry Question

Which of the following is the least stable and its existence is doubtful

Options

(a) SnI₄
(b) CI₄
(c) PbI₄
(d) GeI₄

Correct Answer:

PbI₄

Explanation:

Non-existence of pbI₄ can be explained on the basis of strong oxidising nature of pb⁴⁺. The I⁻ ions are reducing agents., i.e., in presence of this ion, Pb⁴⁺ ion is reduced to pb²⁺ ion. Pb⁴⁺ + 2I⁻ → Pb²⁺ + I₂.
