Question

The acidic, basic and amphoteric oxides, respectively, are:

• A. \( \text{Na}_2\text{O}, \text{SO}_3, \text{Al}_2\text{O}_3 \)
• B. \( \text{Cl}_2\text{O}, \text{CaO}, \text{P}_4\text{O}_{10} \)
• C. \( \text{N}_2\text{O}_3, \text{Li}_2\text{O}, \text{Al}_2\text{O}_3 \)
• D. \( \text{MgO}, \text{Cl}_2\text{O}, \text{Al}_2\text{O}_3 \)

Hint:

Acidic oxides are typically non
metal oxides, basic oxides are metal oxides, and amphoteric oxides can react with both acids and bases. Aluminum oxide (\( \text{Al}_2\text{O}_3 \)) is a common example of an amphoteric oxide.

Answer 1

The Correct Option is C

Step 1: Understanding Acidic, Basic, and Amphoteric Oxides
Acidic Oxides: Oxides of non
metals that react with water to form acids.
Basic Oxides: Oxides of metals that react with water to form bases.
Amphoteric Oxides: Oxides that can react with both acids and bases.
Step 2: Analyzing the Options
Option (A): \( \text{Na}_2\text{O} \) (basic), \( \text{SO}_3 \) (acidic), \( \text{Al}_2\text{O}_3 \) (amphoteric). This option is incorrect because the order is not as required.
Option (B): \( \text{Cl}_2\text{O} \) (acidic), \( \text{CaO} \) (basic), \( \text{P}_4\text{O}_{10} \) (acidic). This option is incorrect because it does not include an amphoteric oxide.
Option (C): \( \text{N}_2\text{O}_3 \) (acidic), \( \text{Li}_2\text{O} \) (basic), \( \text{Al}_2\text{O}_3 \) (amphoteric). This option is correct.
Option (D): \( \text{MgO} \) (basic), \( \text{Cl}_2\text{O} \) (acidic), \( \text{Al}_2\text{O}_3 \) (amphoteric). This option is incorrect because the order is not as required.
Step 3: Matching with the Options
The correct order of acidic, basic, and amphoteric oxides is given in option (C). Final Answer: The correct option is (C) \( \text{N}_2\text{O}_3, \text{Li}_2\text{O}, \text{Al}_2\text{O}_3 \).
