Kinetic Studies on 0—H Bond Fission

Kinetic Studies on 0—H Bond Fission Consider the reaction 

Consider now four different types of reactant radicals, viz., alkoxy, alkylperoxy, alkyl and hydrazyl. The corresponding reference bond strengths are as follows, 0—h =110 kcal mole-1 D00—h =89 kcal mole-1 (from hydrogen peroxide, cf., Foner and Hudson, 1956) Dc H =94 kcal mole-1 (from i-Pr-H, Cottrell, 1954) Z)N H= 76 kcal mole-1 (from hydrazine, Foner and Hudson, 1958). The heats of the four reactions are given in Table 1.
