Nitrating refers to the chemical process of adding nitrate groups to a chemical substance such as an organic compound. Some synonyms for nitrating include nitration, nitrosation, and nitridation, which all essentially involve the same chemical reaction. Nitration involves the addition of one or more nitro groups to a molecule, while nitrosation involves the addition of a nitrogen oxide group. Nitridation refers to the introduction of nitrogen into a substrate, which can lead to the formation of new nitrogen-containing compounds. These synonyms are commonly used in chemistry and are often interchangeable depending on the specific context of the nitrating process.
