MCQ
Fluorine has low electron affinity than chlorine because of
- ✓Smaller radius of fluorine, high density
- BSmaller radius of chlorine, high density
- CBigger radius of fluorine, less density
- DSmaller radius of chlorine, less density
✓
Answer
Correct option: A.
Smaller radius of fluorine, high density
a
Fluorine has low electron affinity than chlorine because of smaller radius of fluorine, high charge density.
Fluorine has low electron affinity than chlorine because of smaller radius of fluorine, high charge density.
There are strong interelectronic repulsions in the relatively compact $2 p$ subshell of fluorine. Hence, the incoming electron does not feel much attraction.
