Arrange the following as per instruction...

Arrange the following as per instructions given in the brackets:
Cl, F, Br, I (increasing order of electron affinity)

A

`Br lt I lt F lt Cl`

B

`I lt Br lt Cl lt F `

C

`Br lt Cl lt I lt F`

D

`F lt Cl lt Br lt I`

Text Solution

Verified by Experts

The correct Answer is:
B
On moving down the group as the atomic size increases, electron affinity decreases. The more the electron affinity, more electronegative is the element.
