Current Question (ID: 7933)

Question:

$\text{The correct order for electron affinity of halogens is :}$

Options:

1. $\text{Br} > \text{F}$
2. $\text{F} > \text{Cl}$
3. $\text{Br} > \text{Cl}$
4. $\text{F} > \text{I}$ (Correct)

Solution:

$\text{HINT: Generally electron affinity decreases down the group.}$\n\n$\text{Explanation:}$\n\n$\text{The electron affinity of F is less than Cl. Hence electron affinity of F is greater than I is the correct option.}$\n\n$\text{Electron affinity}$\n\n$\text{The low value of electron affinity of fluorine is probably due to small size of fluorine atom, i.e. electron density is high which hinders the addition of an extra electron.}$
