A) Rank the conformations of butane in order of increasing energy:

- Anti
- Me-Me Eclipsed
- Me-Me Gauche
- Me-H Eclipsed


B) Explain why each conformation is higher in energy than the previous conformation in the ranking.
(This means three explanations)


C.) Sketch out how energy changes (y-axis) as the conformation changes (x-axis). Copy the below empty diagram to start. Start from the methyl-methyl eclipsed conformation, which we will define for this exercise as 0°, and end at a full rotation (360°). You do not have the calculated energy for every possible conformation, but you do have calculated energy values for important ones and you should use those values as guide points.
Hint: Each key conformation comes after 60° of rotation.

I think this may help. It's not my work, so I won't be able to follow up on these:
