Unformatted text preview: Newman Projections A Way to Analyze Noncyclical Conformations Conformations Conformations are the different positions a molecule can bend into. Atoms and bonds remain the same on the molecule, the only variation is the angles in which certain parts of molecule are bent or twisted. Molecules have conformations with high strain as well as conformations with low strain. High strain conformations are when certain parts of the molecule that repel are forced to be close to one another. Molecules, therefore, want to have a low strain structure. Newman Projections are one way to look at the conformation of a noncyclical molecule. How do I make a Newman Projection? 1) First, you will need a molecule with a small chain of carbons such as this one: 2) Then, you will need to line up two of the center carbons. For this case, we will line up the 2 and 3 carbon as labeled on the above image. The 2 carbon will be in front, and the 3 carbon will be in the back....
