2. (10 pts)When the propylene forms carbocation with the acid, there
are two possible carbocations
H3C─CH+─CH3 and H3C─CH2─CH2+
Which one is more stable?? Briefly explain the possible explanation.
3. (20 pts)Consider a diatomic moleue XY, where the molucular orbitals
are approximated by the linear combination of the atomic orbitals
φx and φy. Suppose that Hxx=-8eV, Hyy=-5eV, Hxy=-2eV, Sxy=0.
Cacultate the energies and the relative cofficients of the two
molucular orbitals.
4. (20 pts)Consider the π system of (cyclic radical) C3H3, where we
number the carbon atoms as atom 1, 2, and 3.Suppose α=H11=H22=H33,
β=H12=H23=H13, S12=S13=S23=0.Draw the energy diagram and the wave
functions of thr three MO.(You can use the calculation result in the
class.)
5. (20 pts)For the ions Mn2+ and Co2+, draw the separate crystal field
energy diagrims for the strong and the weak octahedral fields.
Indicate the total number of unpaired electrons in each case.
6. (20 pts)Given the following MO for CrCl6,draw the qualitative wave
functions for the MO σp and σ*d.
Cr [CrCl6]3- 6 Cl-
