'''Nitryl chloride''' is a volatile inorganic compound with formula ClNO<sub>2</sub>. At standard conditions it is a gas.
==Formation== Nitryl chloride can be formed in the reaction of dinitrogen pentoxide with chlorides or hydrogen chloride:<ref name=atmo /><ref name=struct /> :N<sub>2</sub>O<sub>5</sub> + 2HCl <big>→</big> 2ClNO<sub>2</sub> + H<sub>2</sub>O :N<sub>2</sub>O<sub>5</sub> + NaCl <big>→</big> ClNO<sub>2</sub> + NaNO<sub>3</sub>
==Reactions== Nitryl chloride adds to olefins in a radical reaction.<ref name=OrgRxn />
