Ionic reactions with organic compounds proceed through:

(A) Homolytic bond cleavage

(B) Heterolytic bond cleavage

(D) Primary free radical

(E) Secondary free radical

Choose the correct answer from the options given below:

Option A:
(A) only
Option B:
(C) only
Option C:
(B) only
Correct
Option D:
(D) and (E) only

Answer: C

Step-by-step solution

Ionic reactions involve the formation of charged species (ions). Heterolytic bond cleavage results in one atom retaining both electrons, forming a cation and an anion. This is characteristic of ionic (polar) reactions. Homolytic cleavage produces free radicals, which are involved in radical reactions, not ionic reactions. Options (A), (C), (D), and (E) describe free radical processes, which are not ionic. Thus, only heterolytic bond cleavage (option B) is correct for ionic reactions. Therefore, the correct answer is (B) only, which corresponds to option C in the choices.
