Abstract

The gas-phase photobromination of fluoroethane was investigated in the temperature range 80—150° C in both the presence and absence of chloroethane as an external competitor. The rate constant for α-hydrogen abstraction in CH 3 CH 2 F was redetermined relative to that in CH 3 CH 2 Cl, and the abstraction of β-hydrogen was measured in the internal competition. The relative rates were combined with the known rate parameters for the ...
