Nitryl chloride is a volatile inorganic compound with formula ClNO2. At standard conditions it is a gas.
Formation
Nitryl chloride can be formed in the reaction of dinitrogen pentoxide with chlorides or hydrogen chloride:
:N2O5 + 2HCl → 2ClNO2 + H2O
:N2O5 + NaCl → ClNO2 + NaNO3
Reactions
Nitryl chloride adds to olefins in a radical reaction.
