The correct order of acidic strength :

Options

  1. ACl ₂ O ₇> SO ₂> P ₄ O ₁₀
  2. BK ₂ O > CaO > MgO
  3. CCO ₂> N ₂ O ₅> SO ₃
  4. DNa ₂ O > MgO > Al ₂ O ₃

Correct answer

A. Cl ₂ O ₇> SO ₂> P ₄ O ₁₀

Step-by-step solution

Acidic character of oxide Non-metallic nature of element. Non-metallic character increases along the period. Hence order of acidic character is Cl ₂ O ₇> SO ₂> P ₄ O ₁₀
