Question 8C on Winter 2013 Final Exam states:

"Name the molecule shown in the Newman projection below? What conformation is it in?"


How do you know this is a chair conformation by looking at newman projection?

We see that the C-H bonds are all staggered, so it is in chair conformation. If it were not chair conformation (or is planar conformation), then the bonds would all be eclipsed (pg 112 of organic chem txtbook)
