Information: - Nitrogen dioxide is the chemical compound with the formula . It is one of several nitrogen oxides. is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year. At higher temperatures it is a reddish-brown gas that has a characteristic sharp, biting odor and is a prominent air pollutant. Nitrogen dioxide is a paramagnetic, bent molecule with C point group symmetry. - Nitryl fluoride , NO2F , is a colourless gas and strong oxidizing agent , which is used as a fluorinating agent and has been proposed as an oxidiser in rocket propellants ( though never flown ) . It is a molecular species , not ionic , consistent with its low boiling point . The structure features planar nitrogen with a short N - F bond length of 135 pm . - Nitryl is the nitrogen dioxide (NO) moiety when it occurs in a larger compound. Examples include nitryl fluoride (NOF) and nitryl chloride (NOCl).
