Question

One of the following is not a neutral oxide. This is:

Options

• CO

• H₂O

• N₂O

• Na₂O

Answer 1

Na₂O

Explanation:

Sodium oxide (Na₂O) is a strongly basic oxide, not a neutral one, because it reacts vigorously with water to form the base sodium hydroxide (NaOH). In contrast, carbon monoxide (CO), Water (H₂O), and nitrous oxide (N₂O) are classic neutral oxides that show neither acidic nor basic properties when mixed with water.
