How to draw newman projections from wedge dash
If we start at carbon one, we start up axial, so let's go ahead and put in the axial hydrogens on our Cyclohexane, on our chair conformation. So here is carbon one. We're gonna draw a line straight up and put in a hydrogen. We go to carbon two. We draw a line straight down and put in a hydrogen.Draw the resulting product of attaching a hydride on that face of the molecule as both a Newman projection and as a wedge-dash structure for each enantiomer. Label the configuration of each stereocenter in the resulting hydrobenzoin as either (R) or (S) d) Identify the stereochemical relationship (enantiomeric, diastereomeric, or identical) of ...

Assuming normal valence (e.g. an amine but not a nitro conpound), include the formally nonbonded electron pair as one of the substituents on nitrogen. You can just draw the nitrogen from the centre of the circle using a lesser "wedge" angle on the circle to indicate an eclipsed bond.Starting with a Fischer projection, it's not too hard to convert it to a Haworth once you know a few tricks. For C-2, C-3, and C-4, if the OH is on the right hand side of the Fischer, it will be down in the Haworth. If it is on the left hand side of the Fischer, it will be up in the Haworth. If the sugar is D, draw the C-5 CH 2 OH pointing up.Draw Newman Projections to show the different conformers of 2-chloropentane, focusing on the C_2-C_3 bond. Show all six conformers.

The various projections are just different ways of displaying a three dimensional molecule in two dimensions. They are tools for helping us visualize the molecule and the only time you have to use them would be on a test where they specifically ask you to draw them. That said, Newman projections are useful for figuring out how groups interact when they are bonded to adjacent carbons in a molecule.Here are the pictures of the eclipsed conformations from the video, and our goal is to pick the least stable, but just for practice, let's try drawing all of them as Newman projections. So we'll start with the one on the left here, and we're staring at C2, so that's C2, which we represent by a point.
