Identify the most acidic oxide among the following oxides based on their reaction.

Options

  1. ASO₃
  2. BP₄O₁₀
  3. CCl₂O₇
  4. DN₂O₅

Correct answer

C. Cl₂O₇

Step-by-step solution

As we move from left to right within a period, the acidic character increases. As we move down a group, the acidic character decreases. Order of acidic strength: SO ₃ < P ₄ O ₁₀ < N ₂ O ₅ < Cl ₂ O ₇
