Disproportionation-combination ratios have been obtained for small alkyl radicals produced in the mercury-photosensitized hydrogenation of ethylene, propylene, butene-1, butene-2, and isobutene. For conditions favoring thermalized radicals, kd/k, (ethyl, ethyl) = 0.14, kd/k, (isopropyl, isopropyl) =
Several attempts have been made to correlate the disproportionation and the combination rate constant ratio, k,/k,, of the alkyl radicals with the entropy change of the processes [ 1-31. Bradley [I] made a specific suggestion that the k,/k, ratio is a function of the entropy change of the processes
