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. 88 88 Which of the above sketches correspond to bonding MOS? e (5) 4,5,6 3,7 1,2,7,8 1,7,8 3,4,5,6 (2) (8) -

9A.2 Write the valence bond wavefunction of the o bond in a C-H group of a molecule.

One of the excited states of a C, molecule has the electron configuration: (01,)²(01,*)²(02,)²(02,*)'(T 2,)*(02,)'. What is the bond order of C, in this excited state? C, bond order in excited state: What is the bond order of C, in the ground state? C, bond order in ground state: How does the bond length in this excited state compare to that in the ground state? bond length (excited state) bond length (ground state)
