Question
Among the following oxides which is the most basic:
- MgO
- BaO
- Cu2O
- BeO.
Hint:
Down the group basicity increases.
The correct answer is: BaO
- In general metallic oxides are basic and non metallic oxides are acidic in nature.
- In group 2 down the group basicity increases.
- BeO is insoluble in water and does not easily for hydroxides.
- Down the group oxides are more soluble and easily form bases.
- Hence, BaO is most basic.
