Which of the following oxides is highly basic?
- A \(\mathrm{Cr}_2 \mathrm{O}_3\)
- B \(\mathrm{Al}_2 \mathrm{O}_3\)
- C \(\mathrm{MgO}\)
- D \(\mathrm{Na}_2 \mathrm{O}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{Na}_2 \mathrm{O}\)
Step-by-step Solution
Detailed explanation
Strongly electro positive metals form strongly basic oxides that dissolve in water to give alkalis. \(\mathrm{Na}_2 \mathrm{O}\) has strongly electro positive \(\mathrm{Na}\)-metal that forms \(\mathrm{NaOH}\) in water which is a strong base.
