Arrange the halogens F(2),Cl(2),Br(2),I(...

Arrange the halogens `F_(2),Cl_(2),Br_(2),I_(2)`, in order of their increasing reactivity with alkanes.

A

`I_2 lt Br_2 lt Cl_2 lt F_2`

B

`Br_2 lt Cl_2 lt F_2 lt I_2`

C

`F_2 lt Cl_2 lt Br_2 lt I_2`

D

`Br_2 lt I_2 lt Cl_2 lt F_2`

Text Solution

Verified by Experts

The correct Answer is:
A
Reactivity decreases down the group as the electronegativity or the electrode potential of the halogen decreases down the group. Thus, option (a ) is correct
