Vedclass · Answer

(A) The reducing character of the hydrides of group $V$ elements depends upon the stability of the $E-H$ bond. As we move down the group,the atomic size of the central element increases,which leads to a decrease in the bond dissociation enthalpy and stability of the hydrides. Consequently,the ability to release hydrogen atoms increases,making the reducing character increase down the group. Thus,the correct order of reducing abilities is $NH_3 < PH_3 < AsH_3 < SbH_3 < BiH_3$.

The correct order of reducing abilities of hydrides of $V$ group elements is
