Question:
Which of the following elements are arranged in the correct order of their electron gain enthalpies?
Which of the following elements are arranged in the correct order of their electron gain enthalpies?
Show Hint
Electron gain enthalpy becomes less negative down the group and more negative across a period.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Fluorine has the highest electron gain enthalpy. Oxygen has lower than sulfur due to smaller size and inter-electronic repulsion. Hence the correct order is:
\[
\text{F} \gt \text{S} \gt \text{O} \gt \text{N}
\]
