Correct answer: B
-
Recall the definitions
- Acidic oxides: generally non-metal oxides that form acids with water or react with bases.
- Basic oxides: generally metal oxides that react with acids.
- Amphoteric oxides: oxides that react with both acids and bases.
-
Common examples
- Acidic oxides: , , , , ,
- Basic oxides: , , , ,
- Amphoteric oxides: , ,
-
Check each option in the required order: acidic, basic, amphoteric
Option A: , ,
- is an acidic oxide.
- is a basic oxide.
- is also an acidic oxide, not amphoteric.
Hence, A is incorrect.
Option B: , ,
- is an acidic oxide.
- is a basic oxide.
- is an amphoteric oxide.
Hence, B is correct.
Option C: , ,
- is basic, not acidic.
- is acidic, not basic.
- is amphoteric.
Order is wrong, so C is incorrect.
Option D: , ,
- is basic, not acidic.
- is acidic, not basic.
- is amphoteric.
Order is wrong, so D is incorrect.
-
Final answer
The acidic, basic and amphoteric oxides respectively are: So the correct option is B.
