Chemistry Question from JEE Main 2024 · 30 January, Shift 2

Choose the correct statements about the hydrides of group 15 elements:

1. A: The stability of the hydrides decreases in the order $NH_3 > PH_3 > AsH_3 > SbH_3 > BiH_3$.
2. B: The reducing ability of the hydrides increases in the order $NH_3 < PH_3 < AsH_3 < SbH_3 < BiH_3$.
3. C: Among the hydrides, $NH_3$ is a strong reducing agent while $BiH_3$ is a mild reducing agent.
4. D: The basicity of the hydrides increases in the order $NH_3 < PH_3 < AsH_3 < SbH_3 < BiH_3$. Choose the most appropriate from the options given below:
