Ionic reactions with organic compounds proceed through:
(A) Homolytic bond cleavage
(B) Heterolytic bond cleavage
(C) Free radical formation
(D) Primary free radical
(E) Secondary free radical

Choose the correct answer from the options given below:

(A)(A) only
(B)(C) only
(C)(B) only✓ Correct
(D)(D) and (E) only

Answer: (C)

Solution

Ionic reactions of organic compounds proceed via heterolytic bond cleavage, where both bonding electrons go to one of the two fragments, generating a cation and an anion (or a carbocation/carbanion intermediate). Homolytic cleavage and free-radical formation are characteristic of radical (non-ionic) mechanisms, not ionic ones. So the correct choice is (B) only [heterolytic bond cleavage].
