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

Question

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

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.

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

$R — I > R — B r > R — Cl > R — F$

$R — F > R — Cl > R — B r > R — I$

$R — Cl > R — B r > R — I > R — F$

$R — B r > R — I > R — Cl > R — F$

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.

Q. 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

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.

$R — I > R — B r > R — Cl > R — F$

$R — F > R — Cl > R — B r > R — I$

$R — Cl > R — B r > R — I > R — F$

$R — B r > R — I > R — Cl > R — F$

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.
