A pair of amphoteric oxides is
- A \(\mathrm{Al}_2 \mathrm{O}_3, \mathrm{Li}_2 \mathrm{O}\)
- B \(\mathrm{BeO}, \mathrm{BO}_3\)
- C \(\mathrm{BeO}, \mathrm{MgO}\)
- D \(\mathrm{BeO}, \mathrm{ZnO}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{BeO}, \mathrm{ZnO}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{BeO}, \mathrm{Al}_2 \mathrm{O}_3\) and \(\mathrm{ZnO}\) are amphoteric in nature
\(\mathrm{MgO}\) and \(\mathrm{Li}_2 \mathrm{O}\) are basic in nature whereas \(\mathrm{BO}_3\) is acidic. Thus, the pair of amphoteric oxides are \(\mathrm{BeO}\) and \(\mathrm{ZnO}\).
\(\mathrm{MgO}\) and \(\mathrm{Li}_2 \mathrm{O}\) are basic in nature whereas \(\mathrm{BO}_3\) is acidic. Thus, the pair of amphoteric oxides are \(\mathrm{BeO}\) and \(\mathrm{ZnO}\).
