Which from following compounds is NOT acidic in nature?

Options

  1. ASO ₂
  2. BCO ₂
  3. CN ₂ O ₅
  4. DN ₂ O

Correct answer

A. SO ₂

Step-by-step solution

Oxides are classified as acidic, basic, amphoteric, or neutral. Non-metal oxides are typically acidic, though exceptions exist. SO 2 is an oxide of sulfur. It reacts with water to form sulfurous acid: SO ₂(g) + H ₂ O (l) H ₂ SO ₃(aq) , so it is acidic. CO 2 is an oxide of carbon. It reacts with water to form carbonic acid: CO ₂(g) + H ₂ O (l) H ₂ CO ₃(aq) , so it is acidic. N 2 O 5 is an oxide of nitrogen. It reacts with water to form nitric acid: N ₂ O ₅(s) + H ₂ O (l) 2 HNO ₃(aq) , so it is acidic. N 2 O is also
