1. The problem statement, all variables and given/known data Are these structures equivalent? Here's the professor's rendering: http://i.minus.com/jnojtCx6wYvqD.png [Broken] 3. The attempt at a solution Here's my rendering. The molecule is 1-chloro-2-ethylcyclohexane. I had projected the chlorine out of the page and the ethyl group into the page (opposite of the prof's rendering). And since the chloro is on the first carbon, and in my chair conformation, there are only two possible positions for any attachment to the first carbon - axial up or equatorial down - I made the chlorine axial up (because it's also up in the 2D drawing I made). Similarly, I made the ethyl group axial down (because it's projected into the page according to my 2D drawing, and the alternative is making it equatorial up, which doesn't match my 2D drawing). Is my reasoning correct and is my drawing ultimately correct? Here's my drawing.
