Which of the following orders regarding ionization energy is correct?
- A \(\mathrm{N}>\mathrm{O}>\mathrm{F}\)
- B \(\mathrm{N} < \mathrm{O} < \mathrm{F}\)
- C \(\mathrm{N}>\mathrm{O} < \mathrm{F}\)
- D \(\mathrm{N} < \mathrm{O}>\mathrm{F}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{N}>\mathrm{O} < \mathrm{F}\)
Step-by-step Solution
Detailed explanation
Hints : As IE \(1 \mathrm{~N}>\mathrm{O}\) (because of half filled orbitals of \(\mathrm{N}\) ) and \(\mathrm{O} < \mathrm{F}\) (because of smaller size of \(\mathrm{F}\) )
