For the electron affinity of halogens (with `-ve` sign), which of the following is correct?

A

BrgtF

B

FgtCl

C

BrgtCi

D

Fgt1

Text Solution

Verified by Experts

The correct Answer is:
D
Electron affonity `F,Cl,Br,I`
Electron affinity `-3.6,-3.8,-3.5,-3.2`
The low value of electron affinity of fluorine is probably due to small size of fluorine atom,i.e. electron density is high which hinders the addition of an extra electron.
