HOMOLYTIC :: 1) the symmetrical breaking of a covalent bond in which each departing atom takes one electron from the bonding pair is called HOMOLYTIC cleavage.
2) this type of cleavage leads to the formation of free radicals which are uncharged species bearing unpaired electron.
3) the bond between the two atoms having nearly the same Electronegativity breaks in this way.
4) this takes place favourably in a non-polar solvent .
HETEROLYTC ::: 1) the unsymmetrical breaking of a covalent bond in which one of the departing atoms retains the bonding pair is called a heterolytic cleavage.
2) this type of cleavage leads to the formation of charged species - ions, like Carbocation or carbanion.
3) the bond between the two atoms which differ widely in their Electronegativity breaks in this way.
4) this takes place favourably in a polar solvent
