Question

In the following, the species having the

highest electron gain enthalpy is

1) O 2) O- 3) Cl- 4) N-​

Answer 1

Answer:

Halogens have the highest electron gain enthalpy (electron affinity). Normally electron affinity decreases as we move down the group. However, fluorine has a lower value than chlorine which is due to its small size. Hence, chlorine has the highest electron gain enthalpy.

Hence, the correct option is C
