Question

The oxide of non-metal which is neutral is:

• A. $S{O}_2$
• B. $N{O}_2$
• C. $P_2{O}_3$
• D. $CO$

Answer 1

The correct option is D $CO$

Neutral oxides are the oxides which show neither basic nor acidic properties when they react with water and they do not form salts when reacted with acids or bases.
Carbon monoxide $\left(CO\right),$ nitrous oxide $\left(N_{2}O\right),$ nitric oxide $\left(NO\right)$ are neutral oxides.
