(15 pts) Consider the molecule B2H6. Generate a molecular orbital diagram but this
time using a different approach that draws on your knowledge and ability to put
concepts together. First use VSEPR or some other method to make sure you know
the ground state structure of the molecule. Next, generate an MO diagram for BH2.
Sketch the highest occupied and lowest unoccupied MOs of the BH2 fragment.
These are called frontier orbitals. Now use these frontier orbitals as your basis set
for producing LGO's for B2H6. Since the BH2 frontier orbitals become the LGOS,
you will have to think about what is in the middle of the molecule and treat its basis
as well. Do you arrive at the same qualitative MO diagram as is discussed in the
book? Sketch the new highest occupied and lowest unoccupied MOs for the
molecule (B2H6).
Q8: Propose an efficient synthesis of cyclopentene from cyclopentane.
