Match List I with List II. List I (Oxide) List II (Nature) A. N₂O I. Acidic B. BaO II. Basic C. Al₂O₃ III. Neutral D. Cl₂O₇ IV. Amphoteric Choose the correct answer from the options given below:

Options

  1. AA-I, B-II, C-IV, D-III
  2. BA-III, B-II, C-IV, D-I
  3. CA-III, B-IV, C-II, D-I
  4. DA-I, B-IV, C-II, D-III

Correct answer

B. A-III, B-II, C-IV, D-I

Step-by-step solution

N₂O is a neutral oxide of nitrogen. BaO is an oxide of an alkaline earth metal (barium), hence it is basic in nature. Al₂O₃ reacts with both acids and bases, making it an amphoteric oxide. Cl₂O₇ is an oxide of a halogen (chlorine) in its highest oxidation state, which is strongly acidic. Therefore, the correct matching is A-III, B-II, C-IV, D-I. Answer: A-III, B-II, C-IV, D-I
