Newman Projections

Newman projections are important in organic chemistry to help you understand one aspect of molecular conformations. This video will help you understand everything from Newman projection basics, how to convert Newman to other forms, how to analyze the energy of particular conformations, and of course how to draw an energy diagram.

Included in this series:

  1. Intro to Newman Projections
  2. Projections of Butane
  3. Projections of Substituted Propane
  4. Projections of Multi-Substituted Molecule
  5. Projection to Bond-Line Notation Trick
  6. Converting Newman to Fischer Projections

This video covers the following topics:
– Drawing the Newman Projection from a 3-dimensional molecule in which not all of the atoms are shown
– Comparing energies of the staggered conformations
– Comparing energies of the eclipsed conformations
– 60 degree rotations for a multi-substituted molecule

Video 4 – Projections of Multi-Substituted Molecule Newman Projection Practice Example Video

This video covers the following topics:

Video 5- Projection to Bond-Line Notation TrickNewman Projection to Bond Line Notation Trick by Leah4Sci

This video teaches you my logic-based trick to quickly turn a Newman Projection into a bond-line notation or skeletal structure without the need to rely on your model kit.

 

Video 6 – Converting Newman to Fischer ProjectionsConverting Newman to Fischer Projections Video

This video shows you how to convert from a Newman Projection to a Fischer projection using the long and tedious method followed by my shortcut.
