Identify the alkyl halide that reacts the fastest in an S_N2 reaction. A)1-chloropropane B)1-bromopropane C)1-fluoropropane D)1-iodopropane

Question

Quizplus · Accepted Answer

The reactivity of alkyl halides in an S_N2 reaction follows the trend: RI > RBr > RCl > RF. This is because the rate-determining step in this mechanism involves the departure of the halide ion, which becomes increasingly difficult with increasing bond strength. Therefore, 1-iodopropane will react the fastest in this reaction.
