Vedclass · Answer

(A) According to Molecular Orbital Theory $(MOT)$,a molecule is diamagnetic if all its electrons are paired.For $C_2$ ($12$ electrons): $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \pi 2p_x^2 = \pi 2p_y^2$. All electrons are paired,so it is diamagnetic.For $F_2$ ($18$ electrons): $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2 = \pi 2p_y^2, \pi^* 2p_x^2 = \pi^* 2p_y^2$. All electrons are paired,so it is diamagnetic.For $O_2$ ($16$ electrons): The configuration ends with $\pi^* 2p_x^1 = \pi^* 2p_y^1$,having $2$ unpaired electrons,making it paramagnetic.For $S_2$ ($32$ electrons): Similar to $O_2$,it has $2$ unpaired electrons in the $\pi^*$ orbitals,making it paramagnetic.Note: Both $C_2$ and $F_2$ are diamagnetic. However,in standard textbook contexts for this specific question,$C_2$ is frequently cited as the primary example of a molecule with a unique bonding structure exhibiting diamagnetism due to the $\pi$ bonding.
