The species which are produced by heterolytic bond breaking and can act as electron pair donors are known as:
Correct answer: A. Nucleophiles
- A. Nucleophiles
- B. Cations
- C. Free radicals
- D. Anions
Explanation
A nucleophile is a chemical species that donates an electron pair to form a chemical bond in relation to a reaction. Heterolytic bond cleavage (heterolytic cleavage; heterolysis): Bond breaking in which the bonding electron pair is split unevenly between the products. Heterolytic cleavage often produces at least one ion.Cation is a positively charged ion.Anion is a negatively charged ion.A free radical is an atom, molecule, or ion that has an unpaired valence electron.

About Nucleophilic Substitution
Nucleophilic substitution replaces a leaving group in an alkyl halide when an electron-rich nucleophile attacks the carbon atom. The topic compares SN1 and SN2 mechanisms, including reaction conditions, substrate structure, solvent effects, nucleophile strength, carbocation formation and stereochemical changes, and distinguishes substitution from elimination.
