JEE MAIN - Chemistry (2024 - 31st January Evening Shift - No. 8)
Choose the correct statements from the following
A. All group 16 elements form oxides of general formula $$\mathrm{EO}_2$$ and $$\mathrm{EO}_3$$, where $$\mathrm{E}=\mathrm{S}, \mathrm{Se}, \mathrm{Te}$$ and $$\mathrm{Po}$$. Both the types of oxides are acidic in nature.
B. $$\mathrm{TeO}_2$$ is an oxidising agent while $$\mathrm{SO}_2$$ is reducing in nature.
C. The reducing property decreases from $$\mathrm{H}_2 \mathrm{~S}$$ to $$\mathrm{H}_2$$ Te down the group.
D. The ozone molecule contains five lone pairs of electrons.
Choose the correct answer from the options given below:
Explanation
(A) All group 16 elements form oxides of the $$\mathrm{EO}_2$$ and $$\mathrm{EO}_3$$ type where $$\mathrm{E}=\mathrm{S}, \mathrm{Se}, \mathrm{Te}$$ or $$\mathrm{Po}$$.
(B) $$\mathrm{SO}_2$$ is reducing while $$\mathrm{TeO}_2$$ is an oxidising agent.
(C) The reducing property increases from $$\mathrm{H}_2 \mathrm{S}$$ to $$\mathrm{H}_2$$ Te down the group.
