Question: The order of basic character of given oxides is :...
The order of basic character of given oxides is :
A
Na2O>MgO>CuO>SiO2
B
MgO>SiO2>CuO> Na2O
C
SiO2 >MgO>CuO> Na2O
D
CuO> Na2O >MgO>SiO2
Answer
Na2O>MgO>CuO>SiO2
Explanation
Solution
Higher the metallic character, greater will be the basic character of its oxide (as DEn, difference in
electronegativities between element and oxygen increases).
