प्रश्न
Account for the following :
Acidic character decreases from N2O3 to Bi2O3 in group 15.
उत्तर
Acidic character of oxides of group 15 elements decreases and basicity increases down the group.
As we move down the group, the atomic size increases, electronegativity decreases and metallic character increases. Oxides of Nitrogen and phosphorous are acidic whereas those of As and Sb are amphoteric and that of Bismuth is basic.
