Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The first ionization enthalpy for oxygen is lower than that of nitrogen.
Reason R : The four electrons in 2p orbitals of oxygen experience more electron-electron repulsion.
In the light of the above statements, choose the correct answer from the options given below.
Multiple Choice Options
- A Both A and R are are correct and R is the correct explanation of A.
- B Both A and R are are correct but R is NOT the correct explanation of A.
- C A is correct but R is not correct.
- D A is not correct but R is correct.
Step-by-Step Verified Solution
Nitrogen has half-filled p-orbitals which is stable. Due to this, its 1st ionization energy is more than oxygen.
