Number of unpaired electrons in N2+ is

1. 2
2. 0
3. 1
4. 34

Correct answer: 1

Solution

To determine the number of unpaired electrons in N2+, we use Molecular Orbital Theory. The electronic configuration of N2+ is (σ1s)²(σ*1s)²(σ2s)²(σ*2s)²(π2px)²(π2py)¹. This shows one unpaired electron in the π2py orbital.
