Rates of reaction of atomic oxygen with C2H3F, C2H3Cl, C2H3Br, 1,1‐C2H2F2, and 1,2‐C2H2F2

Rate constants for the reactions of atomic oxygen (O3P) with C2H3F, C2H3Cl, C2H3Br, 1,1‐C2H2F2, and 1,2‐C2H2F2 have been measured at 307°K using a discharge‐flow system coupled to a mass spectrometer. The rate constants for these reactions are (in units of 1011 cm3 mole−1 s−1) 2.63 ± 0.38, 5.22 ± 0.24, 4.90 ± 0.34, 2.19 ± 0.18, and 2.70 ± 0.34, respectively. For some of these reactions, the product carbonyl halides were identified.
