Vedclass · Answer

(A) The reducing character of the hydrides of group $15$ elements depends upon the thermal stability of the hydrides. As we move down the group,the bond dissociation energy decreases due to an increase in the size of the central atom,which leads to a decrease in the stability of the hydrides. Consequently,the ability to release hydrogen atoms increases,making the reducing character increase down the group. Therefore,the correct order of reducing ability is: $BiH_3 > SbH_3 > AsH_3 > PH_3 > NH_3$. Among the given options,the correct order is $BiH_3 > SbH_3 > PH_3 > NH_3$.

The correct order of reducing ability of the following hydrides is:
