Newman Projections of Butane Organic Chemistry Tutorial VideoNewman Projection Series: Video 2
This tutorial video shows how to draw a Newman Projection from a Sawhorse Projection of the butane molecule, starting from both staggered and eclipsed conformations.

Also explained are the different energy levels attained my rotating the molecule in 60 degree increments to 360, and plotted on a potential energy diagram.

  1. the video was great but i have one question at the end when graphing the front of molecule the ch3 was position on top but before it was position at the bottom.

  2. why do you change between ch3 and h3c

    • Same thing drawn from the other direction. H3C implies 3 H atoms bound to C bound to the parent chain but from the left. CH3 has a C to the right of the parent chain and 3 H atoms attached to it

  3. israa chemistry says:

    so nice

  4. I am so grateful that you did this series, it had really helped me a lot. It helps you understand it instead of memorizing what is going on.

I'd love to hear from you - Leave a comment below
