9.18 Would you expect the nonbonding electron-pair domain inNH3 to be greater or less in size than the corresponding onein PH3?

Using the MO diagrams, predict the bond order for the stronger bond in each pair:(a) B2 or B2+(b) F2 or F2+(c) O2 or O22+(d) C2+ or C2−

Consider the following sketches (1-8) representing molecular orbitals (MOS) obtained by combining the sand patomic orbitals on two atoms. As usual, the white and grey lobes correspond to the opposite signs of the wavefunctions. (1) 1, 5 3,7 88 Which of the above sketches correspond to bonding sigma MOS? 1,2 1, 2,8 (2) 4,5,6 (3) (8)

Using the appropriate MO diagram determine the bond orders for: a) F22+ b) F2-
