Question

Which order about ionization enthalpy is correct? *​

Answer 1

Explanation:

The correct order of ionization energy of C,N,O & F is C<O<N<F.

The correct order of ionization energy of C,N,O & F is C<O<N<F.In a period on moving from left to right, the ionization energy increases. This is due to increase in the effective nuclear charge.

The correct order of ionization energy of C,N,O & F is C<O<N<F.In a period on moving from left to right, the ionization energy increases. This is due to increase in the effective nuclear charge.However the ionization energy of O is lower than the ionization energy of N. This is because in case of N an electron is to be removed from stable half filled 2p sub-shell which requires large energy.
