The correct pair of electron affinity order is
- A \(\mathrm{O}>\mathrm{S}, \mathrm{F}>\mathrm{Cl}\)
- B \(\mathrm{O} < \mathrm{S}, \mathrm{Cl}>\mathrm{F}\)
- C \(\mathrm{S}>\mathrm{O}, \mathrm{F}>\mathrm{Cl}\)
- D \(\mathrm{S} < \mathrm{O}, \mathrm{Cl}>\mathrm{F}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{O} < \mathrm{S}, \mathrm{Cl}>\mathrm{F}\)
Step-by-step Solution
Detailed explanation
Second period elements of p-block have lower values of electron affinity than expected due to unusually smaller size.
