__ picture the molecule looking down at an angle toward the carbon-carbon bond.
Any conformation can be specified by its __, the angle between the C-H bonds on the front carbon atom and the C-H bonds on hte back carbon in the Newman projectin. Two of the conformations have special names. The conformation with angle of 0 is acalled __ because the Newman projection shows the hydrogen atoms on the back carbon to be hidden (__) by those on the front carbon. The __, with an angle of 60 degrees, has the hydrogen atoms on the back carbon staggered halfway between the hydrogens on the front carbon. Any other intermediate conformation is called __.
