Solution


Q.

Among group 16 elements, which one does not show –2 oxidation state                [2024]
1 O  
2 Se  
3 Te  
4 Po  

Ans.

(4)

Going down the group, electronegative character increases, thus tendency to show –2 oxidation state decreases from sulphur to polonium. Hence, Po does not show –2 oxidation state.
