Question

Nonmetals react with oxygen to form or ______ or ________

• A. Acidic oxides, neutral oxides
• B. Acidic oxides, basic oxides
• C. neutral oxides, basic oxides
• D. none of the above

Answer 1

The correct option is A

Acidic oxides, neutral oxides

The explanation for the correct answer:

Option (A): Acidic oxides, neutral oxides

• Non-metal reacts with Oxygen to form its oxides which are generally acidic in nature.
• Example: $\underset{\mathrm{Carbon}}{\mathrm{C}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}$
• These oxides further react with water to form oxyacids.
• However, not all non-metallic oxides are acidic some of the oxides are neutral in nature.
• Example: Some Oxides of carbon and Nitrogen like Carbon monoxide$\left(\mathrm{CO}\right)$, Nitrous oxide$\left({\mathrm{N}}_2\mathrm{O}\right)$, and Nitric oxide $\left(\mathrm{NO}\right)$ are neutral in nature.

So, Option (A) is correct. Nonmetals react with oxygen to form an acidic oxide or neutral oxide.
