Question:

$\text{The order of basic character of given oxides is:}$

Options:

1. $\text{Na}_2\text{O} > \text{MgO} > \text{Al}_2\text{O}_3 > \text{CuO}$ (Correct)
2. $\text{MgO} > \text{Al}_2\text{O}_3 > \text{CuO} > \text{Na}_2\text{O}$
3. $\text{Al}_2\text{O}_3 > \text{MgO} > \text{CuO} > \text{Na}_2\text{O}$
4. $\text{CuO} > \text{Na}_2\text{O} > \text{MgO} > \text{Al}_2\text{O}_3$

Solution:

$\text{HINT: Metallic character} \propto \text{Basic nature of oxides}$\n\n$\text{Explanation:}$\n\n$\text{On moving along a period, the tendency to lose electrons decreases and thus, metallic character also decreases. Non-metallic oxides are acidic in nature.}$\n\n$\text{The metallic character of oxides decreases from Na to Cu.}$\n\n$\text{As metallic character increases the basic nature of oxide also increases. Hence, higher the metallic character, higher the basic nature of their oxide.}$\n\n$\text{So, the correct order of basic nature of oxides will be : Na}_2\text{O} > \text{MgO} > \text{Al}_2\text{O}_3 > \text{CuO}$
