Question

As per MO theory last electron of N2 filled in which molecular orbital?


σMO

πMO

2p

Sp

​

Answer 1

Atomic nitrogen has 5 valence electrons and 4 valence orbitals (2s, 2px, 2py, and 2pz). In the Lewis structure there is a triple bond between the nitrogen atoms and a non-bonding pair of electrons on each. This is consistent with the physical properties of N2.
