The correct set that contains all kinds (basic, acidic, amphoteric and neutral) of oxides is:
- \( \text{Na}_2\text{O}, \text{K}_2\text{O}, \text{Al}_2\text{O}_3 \) and \( \text{As}_2\text{O}_3 \)
- \( \text{Al}_2\text{O}_3, \text{As}_2\text{O}_3, \text{CO} \) and \( \text{NO} \)
- \( \text{K}_2\text{O}, \text{Cl}_2\text{O}_7, \text{As}_2\text{O}_3 \) and \( \text{NO} \)
- \( \text{Na}_2\text{O}, \text{Al}_2\text{O}_3 \) and \( \text{CO} \)
The Correct Option is B
Solution and Explanation
- Acidic oxides react with bases to form salts and water. Example: \( \text{CO} \), \( \text{Cl}_2\text{O}_7 \).
- Amphoteric oxides can react with both acids and bases. Example: \( \text{Al}_2\text{O}_3 \), \( \text{As}_2\text{O}_3 \).
- Neutral oxides do not react with either acids or bases. Example: \( \text{NO} \).
Therefore, the correct set is: \[ \text{Al}_2\text{O}_3, \text{As}_2\text{O}_3, \text{CO} \text{ and } \text{NO}. \]
Final Answer: (B) \( \text{Al}_2\text{O}_3, \text{As}_2\text{O}_3, \text{CO} \) and \( \text{NO} \)
