प्रश्न
Give reason.
PbCl4 is less stable than PbCl2.
उत्तर
- Pb has electronic configuration [Xe] 4f14 5d10 6s2 6p2.
- Due to poor shielding of 6s2 electrons by inner d and f electrons, it is difficult to remove 6s2 electrons (inert pair).
- Thus, due to inert pair effect, the +2 oxidation state is more stable than +4 oxidation state. Hence, PbCl4 is less stable than PbCl2.
