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: Define Oxide Types
Acidic Oxides: Non-metal oxides forming acids with water.
Basic Oxides: Metal oxides forming bases with water.
Amphoteric Oxides: Oxides reacting with both acids and bases.
Step 2: Evaluate Options
Option (A): \( \text{Na}_2\text{O} \) (basic), \( \text{SO}_3 \) (acidic), \( \text{Al}_2\text{O}_3 \) (amphoteric). Incorrect order.
Option (B): \( \text{Cl}_2\text{O} \) (acidic), \( \text{CaO} \) (basic), \( \text{P}_4\text{O}_{10} \) (acidic). Lacks 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). Correct.
Option (D): \( \text{MgO} \) (basic), \( \text{Cl}_2\text{O} \) (acidic), \( \text{Al}_2\text{O}_3 \) (amphoteric). Incorrect order.
Step 3: Select Correct Option
Option (C) presents the correct sequence of acidic, basic, and amphoteric oxides.Final Answer: The correct option is (C) \( \text{N}_2\text{O}_3, \text{Li}_2\text{O}, \text{Al}_2\text{O}_3 \).
