Quizplus · Accepted Answer

Based on the given molecular formula, there are 2 nitrogen atoms and 2 sulfur atoms, each with 1 electron in the p orbital. The molecular orbitals formed are sigma bonding (s-s), sigma antibonding (s-s*), pi bonding (p-p), and pi antibonding (p-p*). The configuration in option B correctly shows the placement of electrons for each of these molecular orbitals. The other options have incorrect or incomplete configurations.
