Vedclass · Answer

(A) The acidic strength of oxides increases as the non-metallic character of the central element increases. For non-metallic oxides,the acidic strength increases across a period from left to right. In option $A$,the non-metallic character order is $Cl > S > P$,so the acidic strength order is $Cl_2O_7 > SO_2 > P_4O_{10}$. In option $C$,$Na_2O$ is basic,$MgO$ is basic,and $Al_2O_3$ is amphoteric,so the order is incorrect. In option $D$,$K_2O$,$CaO$,and $MgO$ are all basic oxides,and their basicity decreases as we move from $K$ to $Mg$.

Which of the following is the correct order of acidic strength?
