ESTIMATION OF THE PHYSICO-CHEMICAL DATA OF HYDROCARBON REACTIONS BY RADIOCHEMICAL METHODS.

When alkane hydrocarbons are irradiated their chemical bonds dissociate in the following increasing order: primary less than secondary less than tertiary less than quarternary. The radiolysis of cycloalkanes is enhanced by their strain energy: Rings of 3-4 carbon atoms break up very easily, partly by a multiple C-C bond dissociation, while for C//7-C//1//0 cycloalkanes hydrogenation is more frequent. The radiolysis of alkenes is similar to that of alkanes, but the bond dissociation is influenced by the positive of the pi -bond. The G(H//2) value of aliphatic alkenes can be estimated from the H-increments of G(H//2).
