Electron will be lost from which molecular orbital when N 2 is converted to N 2 + ?
Options
- Aσ * 2 p x
- Bσ 2 p z
- Cπ 2 p x
- Dπ * 2 p x
Correct answer
B. σ 2 p z
Step-by-step solution
This can be done by the molecular orbital theory. First, write the molecular orbital electronic configuration of N 2 molecule. The total number of electrons present in the dinitrogen molecules is = 14 . All the 14 electrons distributed in the bonding and antibonding molecular orbitals given below.
