Which order is true with reference to size of species? (A) Pb < Pb²

1.	Which order is true with reference to size of species? (A) Pb < Pb²⁺ < Pb⁴⁺ (B) Pb⁴⁺ > Pb²⁺ > Pb (C) Pb > Pb²⁺ > Pb⁴⁺ (D) Pb²⁺ < Pb < Pb⁴⁺
Answer» OPTION cExplanation:As we move down the group the LOWER oxidation STATE is more stable than HIGHER O. S due to the relavitistic EFFECT.
