Question:medium

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:

Show Hint

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

  • Both Statement I and Statement II are incorrect
  • Statement I is correct but Statement II is incorrect
  • Statement I is incorrect but Statement II is correct
  • Both Statement I and Statement II are correct
Hide Solution

The Correct Option is B

Solution and Explanation

Statement I: Nitrogen forms ammonia, and similarly, arsenic forms arsine. This statement is correct. Arsenic, much like nitrogen, can produce arsine (AsH₃), a compound with chemical properties comparable to ammonia (NH₃). Statement II: Antimony is incapable of forming antimony pentoxide. This statement is incorrect. Antimony is capable of forming antimony pentoxide (Sb₂O₅), a recognized compound of antimony in its highest (+5) oxidation state.
Therefore, the correct conclusion is (2) — Statement I is accurate, while Statement II is inaccurate.
