Electron will be lost from which molecular orbital when N 2 is converted to N 2 + ?

Options

  1. Aσ * 2 p x
  2. Bσ 2 p z
  3. Cπ 2 p x
  4. 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. N 2 → KK 0 σ 2 s 2 σ * 2 s 2 π 2 p x 2 = π 2 p y 2 σ 2 p z 2 N 2 + → KKσ 2 s 2 σ * 2 s 2 π 2 p x 2 = π 2 p y 2 2 p z 1 As per the molecular orbital electronic confi
