Based on molecular orbital theory, which of the following represents the electronic configuration of the molecule?

1. σ1s²σ*1s²σ2s²σ*2s²σ2p²π2p²=6σ2p
2. π2p²=π2p²σ2p²σ3s²σ*3s²σ3p²
3. π3p²=π3p²π*3p²=3p²
4. The last two electrons remain unpaired, resulting in 2 unpaired electrons.

Correct answer: σ1s²σ*1s²σ2s²σ*2s²σ2p²π2p²=6σ2p

Solution

Option A correctly represents the molecular orbital configuration for a diatomic molecule, following the Aufbau principle and molecular orbital theory. The other options are either incorrectly formatted or do not follow the correct sequence.
