Rationalise the given statements and give chemical reactions : • Lead(II) chloride reacts with Cl_(2) to give PbCl_(4). • Lead(IV) chloride is highly unstable towards heat. • Lead is known not to form an iodide, PbI_(4).

Rationalise the given statements and give chemical reactions : • Lea

1.	Rationalise the given statements and give chemical reactions : • Lead(II) chloride reacts with Cl_(2) to give PbCl_(4). • Lead(IV) chloride is highly unstable towards heat. • Lead is known not to form an iodide, PbI_(4).
Answer» SOLUTION :LEAD(II) CHLORIDE, `PbCl_2` does not react with `Cl_2` to give `PbCl_4`. This is because, DUE to inert-pair effect, the +2 oxidation state of lead is more stable than its +4 oxidation state. In other words, `PbCl_2` is more stable than `PbCl_4`
