Gas phase reactions of hydroxyl radicals with ethane and a series of CI- and F-substituted methanes were studied at atmospheric pressure and over the temperature range 300-400 K. Hydroxyl radicals were produced by pulse radiolysis of water vapour and the decay rate was studied by monitoring the transient light absorption at 3090 A. Arrhenius parameters (A,Ea) for the reaction RH + OH -&gt; R + HOH were obtained for the reactants RH = C2H6, CH3Cl,CH2Cl2,CHFCl2. CFCl2 (CFC-12) which contains  no C-H bonds was found to be inert toward attack by hydroxyl radicals. Since no other tropospheric sink reactions have been reported for CFC-12 its possible impact on the stratospheric ozone remains a controversial problem
