Detailed study has been made of the competitive unimolecular decomposition of several chemically activated radicals 2-methyl hexyl-3, 4-dimethyl pentyl-2 and 5-methyl hexyl-3. These decompose by C-C bond ruptures to give isopropyl and methyl radicals. Disproportionation-recombination ratios of the various radicals were measured. The value of DIso-Pr-H is determined to be 12.7 kcalmole. The rate data are examined on a theoretical model. A summary of bond dissociation values determined by the present method is given. Author
