Question

Which order about ionization enthalpy is correct? *

(a) N>O>F

(b) N<O<F

(c) N>O<F

(d) N<O>F

​

Answer 1

Answer:

among the second period elements the actual ionization enthalpies are in the order Li<B<Be<C<O<N<F<Ne

hope it helps you :)

Answer 2

Answer:

● The correct order of Ionization enthalpy for Nitrogen, Oxygen and Fluorine is O<N<F.

● So option C i.e N>O<F is correct.
