Vedclass · Answer

(C) The elements of group-$15$ are Nitrogen,Phosphorus,Arsenic,Antimony,and Bismuth.As we move down the group,the atomic size increases and electronegativity decreases.Consequently,the metallic character increases,which leads to an increase in the basic character of the oxides.Therefore,the acidic character of the oxides decreases down the group.The order of acidic strength is: $P_2O_3 > As_2O_3 > Sb_2O_3 > Bi_2O_3$.Thus,the increasing order is $Bi_2O_3 < Sb_2O_3 < As_2O_3 < P_2O_3$.

The acidic character of the group-$15$ elements' oxides in increasing order is:
