Example of homolytic cleavage
WebHomolytic fission is also known as homolytic cleavage or homolytic bond homolysis. These expressions are derived from the Greek word ‘homo,’ which means ‘equal breaking.’ The homolytic bond dissociation energy of a molecule is commonly referred to as the energy required to induce homolytic fission in the molecule. WebRadical chain reactions have three distinct phases: initiation, propagation, and termination. The initiation phase describes the step that initially creates a radical species. In most cases, this is a homolytic cleavage event, and takes place very rarely due to the high energy barriers involved. Often the influence of heat, UV radiation, or a ...

WebFor example, the Cl radical formed in the first step quickly reacts with ethane abstraction a hydrogen and generating new radical: The radical is eventually trapped/quenched by … WebExample of Homolytic Fission. ... The bond dissociation energy for homolytic cleavage is higher than for heterolytic cleavage. Bond cleavage between similar atoms, such as H2, or atoms with extremely minor electronegativity differences, such as CH, is the cause of homolytic cleavage. Heterolytic cleavage, on the other hand, is bond breaking ...
WebJan 7, 2015 · An example is the heterolytic cleavage of the C-Br bond in t-butyl bromide. Since Br is more electronegative than C, the electrons move to the Br. We get a t-butyl cation and a bromide anion. Homolytic Cleavage. The word homolytic comes from the Greek homoios, "equal". For example, the homolytic cleavage of a Br-Br bond is http://www.chem.ucla.edu/harding/IGOC/H/homolytic_cleavage.html
