  1. Question 1

    Q1. In Group 14, Tin commonly forms stable +4 compounds, whereas Lead is more stable in the +2 oxidation state. What causes this contrast?

    • A) Lead is more electronegative than Tin
    • B) Tin has a larger atomic radius than Lead
    • C) The inert pair effect is more pronounced in Lead than in Tin
    • D) Tin +2 compounds are more powerful oxidizing agents than Lead +2

    Answer: The inert pair effect is more pronounced in Lead than in Tin

    Explanation: Lead exhibits the inert pair effect more strongly than Tin, making the +2 state more stable for Lead.
