Introduction of nitrogen dioxide

Nitrogen dioxide, also known as peroxide, is typical of a large π bond structure elements.Π-bond containing three electronic, two of which enter into the bond π orbital, an incoming anti-bonding π orbital. Nitrogen dioxide gas for the red-brown at room temperature, soluble in water and has a pungent odor. Nitrogen dioxide inhalation on the lung tissue may have a strong stimulating effect and corrosion. Because of its structural instability, usually with a dimer - nitrogen tetroxide (colorless gas) mixed there constituted an equilibrium mixture.Nitrogen dioxide, nitrous oxide into the heat. Elevated temperature, the balance shifted to the synthesis of nitrogen dioxide; lower the temperature, balanced synthesis of nitrogen tetroxide to the direction of movement.
