Newman Projections and Practice on Newman Projections

WebA Newman projection is a representation of the molecule looking through a C-C single bond. For every Newman projection, you need to specify the bond and the direction you are looking at. For example, for our molecule, we can look through the C1-C2 bond (even though it can be through any bond). The direction is usually shown with an eye symbol: Web5 nov 2024 · Anti-periplanar refers to a periplanar conformation where the dihedral angle between two atoms or groups of atoms is between ±150° and 180°. In texts, anti-periplanar means bonds are anti-coplanar. The image shows butane (C 4 H 10) in a syn-periplanar conformation where the two methyl groups (-CH 3) are lined up with a 180° angle.
