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:

• A. Both Statement I and Statement II are incorrect
• B. Statement I is correct but Statement II is incorrect
• C. Statement I is incorrect but Statement II is correct
• D. Both Statement I and Statement II are correct

Hint:

Antimony (Sb) can form compounds like antimony pentoxide (Sb₂O₅), and arsine (AsH₃) is analogous to ammonia (NH₃) in arsenic chemistry.

Answer 1

The Correct Option is B

Statement I: Like nitrogen that can form ammonia, arsenic can form arsine.
This statement is correct. Arsenic, like nitrogen, can form arsine (AsH₃), which is analogous to ammonia (NH₃) in its chemical properties.
Statement II: Antimony cannot form antimony pentoxide.
This statement is incorrect. Antimony can form antimony pentoxide (Sb₂O₅), which is a well-known compound of antimony in its highest oxidation state (+5).

Thus, the correct answer is (2) — Statement I is correct but Statement II is incorrect.
