Question

Match List-I with List-II:
 

List-I (Oxide)	List-II (Nature)
(A) Cl2O7	(I) Amphoteric
(B) Na2O	(II) Basic
(C) Al2O3	(III) Neutral
(D) N2O	(IV) Acidic

Choose the correct answer from the options given below:

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

Answer 1

The Correct Option is B

 To solve this matching problem, we need to determine the nature of each oxide given in List-I and match it with its corresponding nature in List-II.

1. Cl₂O₇: This is dichlorine heptoxide, an oxide of chlorine. It is known to form acids when it reacts with water, specifically perchloric acid. Therefore, Cl₂O₇ is an acidic oxide. This matches with (IV) Acidic.
2. Na₂O: Sodium oxide is a typical metal oxide, which forms a basic solution when dissolved in water, producing sodium hydroxide. Hence, Na₂O is a basic oxide. This matches with (II) Basic.
3. Al₂O₃: Aluminum oxide is known to exhibit both acidic and basic properties, depending on the reacting substance. It is called an amphoteric oxide. This matches with (I) Amphoteric.
4. N₂O: Nitrous oxide is a neutral oxide because it doesn’t exhibit significant acidic or basic properties and doesn’t significantly change the pH of water. Thus, N₂O is a neutral oxide. This matches with (III) Neutral.

Based on this analysis, the correct matches are:

• A-IV: Cl₂O₇ - Acidic
• B-II: Na₂O - Basic
• C-I: Al₂O₃ - Amphoteric
• D-III: N₂O - Neutral

Therefore, the correct answer is: A-IV, B-II, C-I, D-III.
