1.	Give the chemical reaction as an evidence for each of the following observation? (i) Tin (II) is a reducing agent whereas lead (II) is not (ii) Gallium (I) undergoes disproportionation reaction.
Answer» (i) It is because Pb²⁺ is more stable than Pb⁴⁺ due to inert pair effect whereas Sn⁴⁺ is more stable than Sn²⁺. Therefore Sn²⁺ is good reducing agent 3Ga⁺ → 2Ga + Ga³⁺ (ii) It is because Ga³⁺ is more stable than Ga⁺

Give the chemical reaction as an evidence for each of the following observation? (i) Tin (II) is a reducing agent whereas lead (II) is not (ii) Gallium (I) undergoes disproportionation reaction.

Answer»

(i) It is because Pb²⁺ is more stable than Pb⁴⁺ due to inert pair effect whereas Sn⁴⁺ is more stable than Sn²⁺. Therefore Sn²⁺ is good reducing agent

3Ga⁺ → 2Ga + Ga³⁺

(ii) It is because Ga³⁺ is more stable than Ga⁺
