In the reaction:Which of the following aryl halide is most reactive?
Correct answer: C. Ar-F
- A. Ar-I
- B. Ar-Cl
- C. Ar-F
- D. Ar-Br
Explanation
Since F is most electronegative it will increase the positive charge density on ring carbon atom and will also stabilize the resulting intermediate thus Ar-F is most reactive.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
