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:
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 correct.
B
Both Statement I and Statement II are incorrect.
C
Statement I is correct but Statement II is incorrect.
D
Statement I is incorrect but Statement II is correct.
Explanation
Statement I is correct (arsenic forms arsine $\text{AsH}_3$). Statement II is incorrect because antimony forms antimony pentoxide $\text{Sb}_2\text{O}_5$.
Detailed Solution
Group 15 elements form hydrides of formula $\text{EH}_3$ ($\text{NH}_3, \text{PH}_3, \text{AsH}_3$ / arsine, $\text{SbH}_3, \text{BiH}_3$). Therefore, Statement I is correct. All elements of Group 15 form two types of oxides: trioxides ($\text{E}_2\text{O}_3$) and pentoxides ($\text{E}_2\text{O}_5$). Antimony forms antimony pentoxide ($\text{Sb}_2\text{O}_5$), which makes Statement II incorrect.
