Question

Which of the following species is most reactive in a SN2 reaction?
Options
A CH3CH2Cl
B CH3CH2Br
C CH3CH2I
Correct Answer
D CH3CH2F
Correct Answer

Option C is the correct answer.

Detailed Explanation

In SN2 reactions, the reactivity of alkyl halides follows: R-I > R-Br > R-Cl > R-F. Iodide is the best leaving group because it is the least basic and most polarizable. Therefore, ethyl iodide reacts fastest.

Hint

Which halide is the best leaving group?
