The correct order of reactivity of alkyl halides is.
Correct answer: C. R-I > R-Br > R-Cl > R-F
- A. R-Br > R-CL > R-F > R-I
- B. R-Br > R-F > R-I > R-CI
- C. R-I > R-Br > R-Cl > R-F
- D. R-Cl > R-I > R-Br > R-F
Explanation
The reactivity of alkyl halides towards nucleophilic substitution reactions follows the order:R-I (alkyl iodide) > R-Br (alkyl bromide) > R-Cl (alkyl chloride) > R-F (alkyl fluoride)This order is based on the strength of the carbon-halogen bond, with the weaker bonds being more reactive. The bond strength decreases from R-F (strongest) to R-I (weakest), making R-I the most reactive and R-F the least reactive
