Answer & Solution
Correct Answer
(A) (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
Step-by-step Solution
Detailed explanation
Electron gain enthalpy generally becomes more negative across a period as we move from left to right. Within a group, electron gain enthalpy becomes less negative down a group. When we add an electron to ' \(F\) ' atom, 2 p orbital leads to greater repulsion than adding an…
