Given below are two statements Statement I: Like nitrogen that can form ammonia, arsenic can form arsine.

Question

Given below are two statements:

Statement I: Like nitrogen that can form ammonia, arsenic can form arsine.

Statement II: Antimony cannot form antimony pentoxide. In the light of the above statements, choose the most appropriate answer from the options given below:

1. A. Both Statement I and Statement II are correct
2. B. Both Statement I and Statement II are incorrect
3. C. Statement I is correct but Statement II is incorrect (Correct answer)
4. D. Statement I is incorrect but Statement II is correct

Correct Answer

Option C — Statement I is correct but Statement II is incorrect

Detailed Solution & Explanation

The correct answer is Statement I is correct but Statement II is incorrect.

Key Points

• All group-15 elements form EH$_3$-type hydrides: N forms ammonia (NH$_3$) and As forms arsine (AsH$_3$), so Statement I is correct.
• Group-15 elements form both E$_2$O$_3$ and E$_2$O$_5$ oxides; antimony does form antimony pentoxide, Sb$_2$O$_5$, so Statement II is incorrect.
