Step 1: Determine the molecular orbital diagrams for each diatomic molecule
To classify a diatomic molecule as diamagnetic or paramagnetic, we need to determine if there are any unpaired electrons in the molecular orbital diagram. Diamagnetic molecules have all electrons paired, while paramagnetic molecules have unpaired electrons. Constructing the molecular orbital diagrams for B₂, N₂, F₂, O₂, and C₂ reveals the electron configurations and pairing status.
Step 2: Analyze the electron configurations
B₂: Has two unpaired electrons in the π₂p orbitals.
N₂: Has no unpaired electrons.
F₂: Has no unpaired electrons.
O₂: Has two unpaired electrons in the π*₂p orbitals.
C₂: Has no unpaired electrons.
Step 3: Classify the molecules based on their electron configurations
