Exercise 1: Ethane (6 pts.) Heat of Formation of ethane: Bond Lengths: C-C C-H Bond Angle: C-C- H I S H-C-H Dihedral Angle: H-C-C-H What angles are ideal for this molecule? Do the results exactly match these ideal angles? If not, why not? Consider the sources of even small deviations from the ideal. What dihedral angle would you expect in the lowest energy conformation of ethane? Does this match your result? What is the term used to describe the shape of this conformer?
