STANDARD Chemistry Reactivity of Alkyl Halides MCQ Question
The order of reactivity of various alkyl halides towards nucleophilic substitution follows the order
R—I > R—Br > R—Cl > R—F
R—F > R—Cl > R—Br > R—I
R—Cl > R—Br > R—I > R—F
R—Br > R—I > R—Cl > R—F
Correct Answer
Detailed Explanation
The alkyl halides are very reactive due to highly polarised C-X bond with a large difference in electronegativities of carbon and halogen atoms. The order of reactivity is iodides > bromides > chlorides > fluorides.
