Question

To synthesize the given compound via an $S_{N}2$ reaction, themost appropriate combination is:

• A.
• B.
• C.
• D. None of the above

Answer 1

The correct option is C

The given compound is a thioether with a sulphur atom surrounded by two alkyl groups. For best $S_{N}2$ results:

Iodide is a terrific leaving group and the substrate - $C{H}_{3}C{H}_{2}I$ is primary. For $S_{N}2$,
the substrate is ideally as less hindered as possible.
