Which one of the following cannot form an amphoteric oxide?

Options

  1. AAl
  2. BSn
  3. CSb
  4. DP

Correct answer

D. P

Step-by-step solution

Phosphorus being a non-metal always forms acidic oxides like P ₂ O ₃, P ₅ O ₁₀ , etc. Al ₂ O ₃, SnO and Sb ₂ O ₃ are amphoteric oxides i.e., react with acids as well as bases.
