Question

identify the correct name for the compound no₂ which is a red - brown colored air pollutant that results from the burning of fuel.
options:

• nitrogen oxide
• dinitrogen monoxide
• nitrogen dioxide
• nitrogen oxate
• nitrate

Explanation:

To name the compound \( \text{NO}_2 \), we use the rules for naming covalent compounds. The first element is nitrogen (N), and the second is oxygen (O). The prefix for 1 (nitrogen, no prefix as it's the first element with one atom) and for 2 (oxygen) is "di-", and the suffix for oxygen in oxides is "-oxide". So we name it nitrogen dioxide.

Answer:

C. nitrogen dioxide
