Question 40

Given below are two statements:
Statement (I) : Oxygen being the first member of group 16 exhibits only -2 oxidation state.
Statement (II) : Down the group 16 stability of +4 oxidation state decreases and +6 oxidation state increases.
In the light of the above statements, choose the most appropriate answer from the options given below:

Statement I: "Oxygen being the first member of group 16 exhibits only -2 oxidation state."

This is incorrect. Oxygen can also show -1 (in peroxides like $$H_2O_2$$), 0 (in $$O_2$$), and +2 (in $$OF_2$$).

Statement II: "Down the group 16 stability of +4 oxidation state decreases and +6 oxidation state increases."

This is incorrect. Actually, down the group, due to the inert pair effect, the stability of +6 oxidation state decreases and +4 oxidation state becomes more stable (e.g., Po prefers +4 over +6).

Both statements are incorrect. The answer corresponds to Option (3).
