This diagram represents the atomic and molecular orbitals for a fictional heteronuclear diatomic. E Orbital A : . . . . . . . . . . . . . . . . . . . . . . . . . .. . . . . . . . . . . . . . * . . . . . . . . . . . . . . . . . . . . . . . . 1h 4 4................. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ..:: : ::;; Orbital B It ...... " . . . . . ....... . . . . . . ......... Orbital C Of the three circled orbitals, orbitals A only * represent molecular orbitals, while others represent atomic orbitals. [0.5 mark] Orbital A is o orbital + . [1 mark] Orbital B is norbital * . [1 mark] Orbital C is n orbital + . [1 mark] The electronic configuration specified above for the MOLECULE is in the V mark] ground state because Hund's rule and Aufbau principle are obeyed The bond order for the molecular electronic configuration specified abo excited electronic state because Hund's rule is disobeyed excited electronic state because Aufbau principle is disobeyed excited electronic state because both Hund's rule and Aufbau principle are disobeyed
