Which of the following diatomic species are correctly matched with their magnetic nature (paramagnet — Chemical Bonding Chemistry Question

💡 Solution & Explanation

According to MOT configurations: $O_2$ has 2 unpaired electrons in its $\pi^*$ orbitals (Paramagnetic). $N_2$ has all 14 electrons paired (Diamagnetic). $B_2$ has 10 electrons with 2 unpaired electrons in degenerate $\pi$ orbitals (Paramagnetic). $C_2$ has 12 electrons, entirely paired in $\pi$ bonding orbitals, making it Diamagnetic (not Paramagnetic).
