Vedclass · Answer

(A) The stability of hydrides of Group $15$ elements decreases down the group. As the size of the central atom increases from $N$ to $Bi$,the $M-H$ bond length increases,which leads to a decrease in the bond dissociation enthalpy. Therefore,the thermal stability follows the order: $NH_3 > PH_3 > AsH_3 > SbH_3 > BiH_3$. Thus,the correct option is $A$.

Which of the following is the correct order of stability of hydrides of Group $15$ elements?
