Classification of Free Radicals Free radicals are also classified as primary (1°) , secondary (2°) and tertiary (3°) according as the carbon carrying the unpaired electron is primary, secondary … [Read more...] about Free Radicals

Inductive and Electromeric Effect
Fission of a covalent bond Homolytic fission If a covalent bonds breaks in such a way that each atom takes away one electron of the shared pair, it is called homolytic or symmetrical fission. Homolytic fission is usually indicated by a fish arrow which denotes a one electron displacement. For Ex: The neutral chemical species which contain an odd or unpaired … [Read more...] about Inductive and Electromeric Effect
