The order of reactivity of the given haloalkanes towards nucleophile is :
Updated On: Jul 28, 2024
- $RI > RBr> RCl$
- $RCl > RBr > RI$
- $RBr > RCl > R$
- $RBr > RI > RCl$

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
For a given alkyl group, the order of reactivity is
$\frac{R ??> R ?? r>R ??1>R ??}{increasing\, bond\, energy}$
decreasing halogen reactivity.
This order depends on the carbon-halogen bond energy; the carbon-fluorine bond energy is maximum and thus fluorides are least reactive while carbon-iodine bond energy is minimum hence iodides are most reactive.
