A) High ionization enthalpy of fluorine
B) Smaller size of chlorine atom
C) Smaller size of fluorine atom
D) Bigger size of 2p orbital of fluorine
Correct Answer: C
Solution :
[c] The electron gain enthalpy order for halogens is \[Cl>F>Br>I\] Due to small size of fluorine the extra electron to be added feels more electron- electron repulsion. Therefore fluorine has less value for electron affinity than chlorine.You need to login to perform this action.
