So given 2-pentanol, I always thought that a Newman projection of it was looking down the C2-C3 axis (with C2 being the front carbon and C3 being the back carbon). In the attached picture, B is the answer. It shows the -OH attached to the back carbon (which I understand can still be C2, you're just drawing it from the other orientation).
First question: Is a newman projection always looking down the C2-C3 axis?
Second: Just to verify, you can draw newman projections "backwards"?; for example, I would have drawn the lowest energy conformation differently, with C2 (one with -OH) being the front carbon.
