Match the following oxides with their nature. Column-I (Oxide) (a) (b) (c) (d) Column-II (Nature) (i) Basic (ii) Neutral (iii) Acidic (iv) Amphoteric Which one of the following is correct?

Answer: (D) (a)-(ii); (b)-(i); (c)-(iv); (d)-(iii). \textbf{Answer:} (D) (a)-(ii); (b)-(i); (c)-(iv); (d)-(iii).

  1. A.(a)-(iii); (b)-(iv); (c)-(i); (d)-(ii)
  2. B.(a)-(iv); (b)-(iii); (c)-(ii); (d)-(i)
  3. C.(a)-(i); (b)-(ii); (c)-(iii); (d)-(iv)
  4. D.(a)-(ii); (b)-(i); (c)-(iv); (d)-(iii)✓

Correct Answer

(D) (a)-(ii); (b)-(i); (c)-(iv); (d)-(iii)

Solution & Explanation

\textbf{Answer:} (D) (a)-(ii); (b)-(i); (c)-(iv); (d)-(iii). \textbf{Solution:} is a neutral oxide, so (a)-(ii). is the oxide of an s-block metal, so it is basic, so (b)-(i). reacts with both acids and bases, so it is amphoteric, so (c)-(iv). has chlorine in its highest oxidation state (), so it is acidic, so (d)-(iii).
