Vedclass · Answer

(A) The basic nature of oxides depends on the metallic character of the element. As metallic character increases,the electron-donating tendency increases,making the oxide more basic.$Na_2O$ is strongly basic (alkali metal oxide).$MgO$ is basic (alkaline earth metal oxide).$Al_2O_3$ is amphoteric.$CuO$ is weakly basic (transition metal oxide).Thus,the decreasing order of basic nature is $Na_2O > MgO > Al_2O_3 > CuO$.

The order in which the following oxides are arranged according to decreasing basic nature is
