The reaction of F atoms with CH₂BrCl was studied using a pulsed radiolysis technique and found to proceed via two channels: direct hydrogen abstraction and adduct formation. The adduct exists in equilibrium with F atoms and CH₂BrCl. The equilibrium constant K₄ = [Adduct]/([CH₂BrCl][F]) = (4.2 ± 1.0) × 10^-16 cm³molecule^-1. In 1000 mbar total pressure of SF₆ at 294 ± 2 K, the yield of the adduct is 68 ± 11% and the overall rate constant for reaction of F atoms with CH₂BrCl is k₄ (1000 mbar) = (3.6 ± 0.9) × 10^-11 cm³ molecule^-1 s^-1. The adduct reacts with NO with a rate constant of (2.09 ± 0.41) × 10^-11 cm³ molecule^-1 s^-1. The atmospheric fate of the alkoxy radical CHBrClO is Br atom elimination, which occurs at a rate estimated to be >2 × 10⁶ s^-1 in 700 Torr of air at 295 K. Relative rate techniques were used to measure k(Cl + CH₂BrCl) = (4.2 ± 0.5) × 10-¹³ and k(F + CH₂BrCl → CHBrCl + HF) = (1.2 ± 0.4) × 10^-11 cm³ molecule^-1 s^-1. These results are compared to the available literature data.
