WebHomolytic fission. The fission of covalent bond such that , one of the electrons of the shared pair in a covalent bond goes with each of the bonded atoms.Thus in this type of cleavage ,the movement of a single electron takes place instead of an electron pair.Homolytic cleavage produces free radical.
