When a covalent bond undergoes heterolytic cleavage, it can produce
cations
Anions
Free radicals
Both a and b
Heterolytic Covalent bond fission (cleavage ) -
The shared pair is taken away by one of the more electronegative atoms.
Hydrolytic products are cation and anion.
Free radical is obtained when a covalent bond cleans in homolytic manner cations and anions are formed by heterolytic cleavage of covalent bonds.
Therefore, option (4) is correct.
