Identify the name for NO.

Identify the name for NO.

• A. Nitrogen dioxide
• B. Nitrogen oxide
• C. Nitrogen monoxide
• D. Nitrosyl

Answer: (C)

The correct name for NO is nitrogen monoxide. In this compound, nitrogen (N) has a oxidation state of +2, and oxygen (O) has an oxidation state of -2. The "mono-" prefix in "monoxide" indicates that there is one oxygen atom in the compound. Using systematic naming conventions in chemistry, the name reflects the number of each type of atom present. Since NO is composed of one nitrogen atom and one oxygen atom, the name combines the name of the element nitrogen and the prefix "mon-" for one, plus "oxide" to denote the presence of oxygen. This distinguishes it from other nitrogen oxides, such as nitrogen dioxide (which would be NO2), where the presence of two oxygen atoms would require a different prefix. In contrast, terms like "nitrogen dioxide" or “nitrosyl” do not apply to this specific molecule, as they refer to different compounds. Understanding the use of prefixes and the rationale behind naming different compounds is crucial for accurate chemical nomenclature.
