Match the oxide given in Column-A with its property given in Column-B: Column-A: (i) Na2O (ii) Al2O3 (iii) N2O (iv) Cl2O7 Column-B: (a) Neutral (b) Basic (c) Acidic (d) Amphoteric Which of the following options has all correct pairs?

Correct answer: (D) (i)-(b), (ii)-(d), (iii)-(a), (iv)-(c). Answer: (D) (i)-(b), (ii)-(d), (iii)-(a), (iv)-(c) Solution: The nature of oxides is a periodic property: Na2O (an s-block metal oxide) is basic (b). Al2O3 is amphoteric (d). N2O is a neutral oxide (a). Cl2O7 (highest oxidation-state oxide of a non-metal) is acidic (c). Hence the correct matching is (i)-b, (ii)-d, (iii)-a, (iv)-c.

B.(i)-(c), (ii)-(b), (iii)-(a), (iv)-(d)
C.(i)-(a), (ii)-(d), (iii)-(b), (iv)-(c)
D.(i)-(b), (ii)-(d), (iii)-(a), (iv)-(c)✓

Correct Answer

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

Solution & Explanation

\textbf{Answer:} (D) (i)-(b), (ii)-(d), (iii)-(a), (iv)-(c) \textbf{Solution:} The nature of oxides is a periodic property: $Na X_{2} O$ (an s-block metal oxide) is basic $\to$ (b). $Al X_{2} O X_{3}$ is amphoteric $\to$ (d). $N X_{2} O$ is a neutral oxide $\to$ (a). $Cl X_{2} O X_{7}$ (highest oxidation-state oxide of a non-metal) is acidic $\to$ (c). Hence the correct matching is (i)-b, (ii)-d, (iii)-a, (iv)-c.
