1. CH 4-4: Newman Projections How to draw a Newman Projection for butane
Newman Projection: 2-Dimensional (2-D) way to represent 3-Dimensional (3-D) conformational changes due to rotation at a specific C-C bond.

2. Using the Newman Projection for butane to demonstrate C-C bond rotation.

3. Review Problem
1) Draw a Newman Projection for this molecule, looking down the C-C bond specified;
2) Is this the most stable conformer? If not, perform a C-C bond rotation and draw the Newman projection of the most stable conformer;
3) Name this compound.
