Which of the following is NOT an oxidation product of a primary amine?

Step-by-step solution

Primary amines can undergo oxidation to form various products depending on the nature of the oxidizing agent. Oxidation of a primary amine ( R-NH₂ ) with Caro's acid ( H₂SO₅ ) or hydrogen peroxide ( H₂O₂ ) yields a hydroxylamine ( R-NHOH ). Further oxidation of the hydroxylamine produces a nitroso compound ( R-NO ). Strong oxidizing agents like potassium permanganate ( KMnO₄ ) or peroxy acids can oxidize primary amines all the way to nitro compounds ( R-NO₂ ). Since hydroxylamines, nitroso compounds, and nitro comp
