A) \[F<Cl<Br<I\]
B) \[Cl<F<Br<I\]
C) \[KBr<Cl<F\]
D) \[Cl<Br<I<F\]
Correct Answer: B
Solution :
The correct order of electron gain enthalpy\[\Delta H\](with + sign) of the halogen atom is \[Cl<F<Br<I\] The reason that fluorine has a less negative electron affinity than chlorine is relatively small size of F atom resulting in the repulsions (electron-electron) to the entering electron.
