The order of basic character of given oxides is:

A

`Na_2O gt MgO gt CuO gt SiO_2`

B

`MgO gt SiO_2 gt CuO gt Na_2O`

C

`SiO_2 gt MgO gt CuO gt Na_2O`

D

`CuO gt Na_2O gt MgO gt SiO_2`

Text Solution

Verified by Experts

The correct Answer is:
A
Higher the metallic character, greater will be the basic character of its oxide as `Delta E` (difference in electronegativities between element and oxygen) increases.
