The correct order of reactivity of halogens is

A

`F gt Cl gt Br gt I`

B

`F lt Cl gt Br lt I`

C

`F lt Cl lt Br lt I`

D

`F lt Cl lt Br gt I`

Text Solution

Verified by Experts

The correct Answer is:
A
We know that atomic no. of fluorine (F), chlorine (Cl), Bromine (Br) and Iodine (I) are 9, 17, 35 and 53 respectively. Therefore correct reactivity of halogens is `F gt Cl gt Br gt I`.
