JEE CHEMISTRY MCQ: P-BLOCK ELEMENTS

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

A. The stability of the hydrides decreases in the order $\mathrm{NH}_3 > \mathrm{PH}_3 > \mathrm{AsH}_3 > \mathrm{SbH}_3 > \mathrm{BiH}_3$

B. The reducing ability of the hydride increases in the order $\mathrm{NH}_3 < \mathrm{PH}_3 < \mathrm{AsH}_3 < \mathrm{SbH}_3 < \mathrm{BiH}_3$

C. Among the hydrides, $\mathrm{NH}_3$ is strong reducing agent while $\mathrm{BiH}_3$ is mild reducing agent.

D. The basicity of the hydrides increases in the order

$\mathrm{NH}_3 < \mathrm{PH}_3 < \mathrm{AsH}_3 < \mathrm{SbH}_3 < \mathrm{BiH}_3$
