Hello there!

I having trouble understanding the relationship between dipole moment and the heat of formation. How do these two relate; for instance, in the reduction of camphor to isoborneol and borneol?

In addition, How does the dipole moment changing for a compound like benzil from 0-180 degrees, change its energy. As the dipole moment goes up the energy goes down, and then at 125 degrees the energy begins to go back up, why is that?
