Which of the following orders regarding ionization energy is correct?

  1. A \(\mathrm{N}>\mathrm{O}>\mathrm{F}\)
  2. B \(\mathrm{N} < \mathrm{O} < \mathrm{F}\)
  3. C \(\mathrm{N}>\mathrm{O} < \mathrm{F}\)
  4. D \(\mathrm{N} < \mathrm{O}>\mathrm{F}\)
Verified Solution

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 \(\mathrm{F}\) )
