Vedclass · Answer

(B) The basic nature of oxides depends on the metallic character of the element. As we move from left to right across a period in the periodic table,the metallic character decreases and the non-metallic character increases. Consequently,the basic nature of the oxides decreases,and the acidic nature increases. For the given elements $(Mg, Al, S, Cl)$,the order of metallic character is $Mg > Al > S > Cl$. Therefore,the order of decreasing basic nature of their oxides is $MgO > Al_2O_3 > SO_3 > Cl_2O_7$.

Which of the following is the correct order of gradually decreasing basic nature of the oxides?
