$A$. 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 hydrides 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 $\mathrm{NH}_3<\mathrm{PH}_3<\mathrm{AsH}_3<\mathrm{SbH}_3<\mathrm{BiH}_3$Choose the most appropriate from the option given below:
$(I)$ ${P_4} + S{O_2}C{l_2} \to $
$(II)$ ${P_4} + SOC{l_2} \to $
$(III)$ $PC{l_5} + S{O_2} \to $
$(IV)$ $PC{l_5} + {C_2}{H_5}OH \to $
(Henry's law constant for $\mathrm{CO}_{2}$ at $298\, \mathrm{~K}$ is $1.67 \times 10^{3}$ $bar$)
