The Correct Option is B
Approach Solution - 1
- CO (Carbon monoxide) is a neutral oxide, hence not an acidic oxide.
- GeO (Germanium oxide) is an acidic oxide, as it reacts with water to form an acidic solution.
- SnO (Tin(II) oxide) is amphoteric, meaning it can react both as an acid and a base.
- PbO (Lead(II) oxide) is amphoteric as well, reacting both with acids and bases.
Thus, the correct acidic oxide among the given options is GeO.
The correct answer is option (2) GeO.
- GeO (Germanium oxide) is an acidic oxide, as it reacts with water to form an acidic solution.
- SnO (Tin(II) oxide) is amphoteric, meaning it can react both as an acid and a base.
- PbO (Lead(II) oxide) is amphoteric as well, reacting both with acids and bases.
Thus, the correct acidic oxide among the given options is GeO.
The correct answer is option (2) GeO.

Approach Solution -2
Step 1: Understand the types of oxides.
Oxides can be classified as acidic, basic, amphoteric, or neutral based on their chemical behavior:
- Acidic oxides react with water to form acids or react with bases to form salts.
- Basic oxides react with acids to form salts.
- Amphoteric oxides can react both with acids and bases.
- Neutral oxides generally do not react with acids or bases.
Step 2: Analyze Carbon monoxide (CO).
- CO is a neutral oxide.
- It does not react significantly with acids or bases.
- Hence, it is not an acidic oxide.
Step 3: Analyze Germanium oxide (GeO).
- GeO reacts with water to form acidic solutions.
- It reacts with bases to form germanates.
- Therefore, GeO behaves as an acidic oxide.
Step 4: Analyze Tin(II) oxide (SnO).
- SnO shows amphoteric behavior.
- It reacts with acids to form tin salts.
- It also reacts with bases to form stannites.
Step 5: Analyze Lead(II) oxide (PbO).
- PbO is also amphoteric.
- It reacts with acids and bases forming corresponding salts.
Step 6: Conclusion.
Among the given oxides:
- CO is neutral.
- GeO is acidic.
- SnO and PbO are amphoteric.
Thus, the correct acidic oxide is GeO.
The correct answer is option (2) GeO.
