Vedclass · Answer

(A) $I$. In a period,from left to right,the metallic character decreases,so the basic nature of oxides decreases.$II$. In a group,from top to bottom,the metallic character increases,so the basic nature of oxides increases.$Na, Mg$,and $Al$ are in the same period ($3^{rd}$ period). The order of basic nature is $Na_2O > MgO > Al_2O_3$.$Na$ and $K$ are in the same group ($1^{st}$ group). Since $K$ is below $Na$,the basic nature of $K_2O > Na_2O$.Combining these,the correct order of increasing basic nature is $Al_2O_3 < MgO < Na_2O < K_2O$.

List-$I$ (Oxide)	List-$II$ (Nature)
$A. Cl_2O_7$	$I. Amphoteric$
$B. Na_2O$	$II. Basic$
$C. Al_2O_3$	$III. Neutral$
$D. N_2O$	$IV. Acidic$

Which one of the following orders presents the correct sequence of the increasing basic nature of the given oxides?
