STANDARD Chemistry Reactivity of Alkyl Halides MCQ Question

Type: MCQ-conceptual-Medium-Class 12

The order of reactivity of various alkyl halides towards nucleophilic substitution follows the order

A

R—I > R—Br > R—Cl > R—F

B

R—F > R—Cl > R—Br > R—I

C

R—Cl > R—Br > R—I > R—F

D

R—Br > R—I > R—Cl > R—F

Correct Answer

Option A

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.
