Which one of the following oxides is neutral?

Correct option is A

The correct answer is: (a) CO
Carbon monoxide (CO) is a neutral oxide.
SnO₂ → acidic
ZnO → amphoteric
SiO₂ → acidic
CO → neither acidic nor basic → neutral
Information Booster:
• Neutral oxides include CO, N₂O, and H₂O
• Acidic oxides react with bases, basic oxides react with acids.
• Amphoteric oxides (like ZnO, Al₂O₃) react with both acids and bases.
