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.
