•: Rate coefficients for Cl-reaction with C_xF_2x+1CHdouble bond; length as m-dash" data-inlimg="/entities/dbnd" src="/sd/grey_pxl.gif" class="glyphImg imgLazyJSB">CH₂ (HFOs) at 298 K are determined.
•: The atmospheric removal of HFOs initiated by Cl compete with OH reactions at dawn.
•: Main reaction product: C_xF_2x+1C(O)CH₂Cl, i.e. reaction mechanism through Cl- addition to the double bond.
•: Product CF₃C(O)CH₂Cl reacts slowly with OH radicals, but UV photolysis is important.
•: Minor products: C_xF_2x+1CHO, C_xF_2x+1CHOHCH₂Cl and CF₂O.
