NEET CHEMISTRYOrganic Chemistry – Some Basic Principles and Techniques Easy

Question

Match the following oxides with their nature:

Column I (a) CO (b) BaO (c) Al₂O₃ (d) Cl₂O₇

Column II (i) Basic (ii) Neutral (iii) Acidic (iv) Amphoteric

A

(a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)

B

(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)

C

(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)

D

(a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)

Step-by-Step Solution

  1. Analyze CO (Carbon Monoxide): It is a non-metal oxide that does not react with acids or bases to form salts. Hence, it is Neutral (matches ii).
  2. Analyze BaO (Barium Oxide): Barium is a Group 2 alkali earth metal. Metal oxides, especially of electropositive elements, are Basic (matches i).
  3. Analyze Al₂O₃ (Aluminium Oxide): Aluminium oxide reacts with both acids (forming aluminium salts) and bases (forming aluminates). Hence, it is Amphoteric (matches iv).
  4. Analyze Cl₂O₇ (Dichlorine Heptoxide): Chlorine is a non-metal in a high oxidation state (+7). Non-metal oxides are generally acidic, and high oxidation states enhance acidity. It dissolves in water to form perchloric acid. Hence, it is Acidic (matches iii).
  5. Conclusion: The correct sequence is a-ii, b-i, c-iv, d-iii.
