Quizplus · Accepted Answer

The reaction is a substitution reaction of a primary halide with a strong nucleophile. The primary halide will undergo SN2 mechanism, which involves the attack of the nucleophile on the electrophilic carbon and simultaneous expulsion of the leaving group. In this case, the most favorable leaving group is iodide due to its larger size and weaker bond with carbon. Among the four choices, only option III depicts this mechanism with the substitution of iodide as the major product. Therefore, the correct answer is C.
