In heterolytic fission, the shared pared of electron is carried away by one atom, which leads to development of poles or polarizattion occurs. This is more signification when two atoms have highe difference in electronegativity. example CH3Cl , Cl being more electronegative than carbon, walks away with shared pair of electron, thus acquiring an extra electron, which makes Cl- ion and CH3+ (Carbocations).
In homolytic fisssion, both the atoms takes back their electron which they had shared during formation of covalent bond, thus no polarization occurs. This is occuring when the two atoms are of close electronegativity so pull on electron is nullified.
