प्रश्न
Rationalise the given statement and give a chemical reaction:
Lead (IV) chloride is highly unstable towards heat.
उत्तर
On moving down group IV, the higher oxidation state becomes unstable because of the inert pair effect. Pb(IV) is highly unstable and when heated, it reduces to Pb (II).
\[\ce{PbCl_{4(l)} ->[\Delta] PbCl_{2(s)} + Cl_{2(g)}}\]
