Notes:
The 147 nm photolysis of 3,3 dimethylbut-1-ene leads mainly to the formation of very hot (≅375 kJ/mol) α,α-dimethallyl radicals. On the other hand, that of 3-methyl-cis-and trans-pentene-2, as well as that of 2,3-dimethylbut-1-ene is a source of very hot α,β-dimethallyl radicals. These allylic radicals are coolled down using pressure and are allowed to combine with available methyl radicals. From the formation of various C6H12 products, it is concluded that the very hot α,α- radical isomerizes towards the α,β-structure at low pressures and vice versa. The equilibrium constant of the following process has been evaluated to be 1.72 ± 0.30. \documentclass{article}\pagestyle{empty}\begin{document}$${\rm CH}_3{\rm C}({\rm CH}_3){\rm CHCH}_2 ^ * \Leftrightarrow {\rm CH}_2 {\rm C}({\rm CH}_{\rm 3}){\rm CHCH}_3 ^ *$$\end{document}
