Question:
Which of the following species has the highest electron affinity?
Show Hint
Electron affinity generally increases as you move across a period from left to right, but the trend can be influenced by electron-electron repulsion.

The Correct Option is
C
Solution and Explanation
The electron affinity of oxygen is higher than that of \( F^- \) and \( Cl^- \) because of the electron repulsion in the \( F^- \) ion, which makes it less stable. \( O^- \), being smaller and less repulsive, has a higher electron affinity.
