Which one of the following cannot form an amphoteric oxide?
- A \(\mathrm{Al}\)
- B \(\mathrm{Sn}\)
- C \(\mathrm{Sb}\)
- D \(\mathrm{P}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{P}\)
Step-by-step Solution
Detailed explanation
Phosphorus being a non-metal always forms acidic oxides like \(\mathrm{P}_2 \mathrm{O}_3, \mathrm{P}_5 \mathrm{O}_{10}\), etc. \(\mathrm{Al}_2 \mathrm{O}_3, \mathrm{SnO}\) and \(\mathrm{Sb}_2 \mathrm{O}_3\) are amphoteric oxides i.e., react with acids as well as bases.
