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.Aug 7, 2017 · Drawing a Newman Projection. 1. Determine which two carbon atoms are being studied. A Newman Projection focuses on one specific bond of the molecule, and note which atoms are attached to these carbon atoms. Add an eye with an arrow looking down the carbon-carbon bond being studied. Example: 2-3 means looking down the carbon 2 and carbon 3 bond.

The conformations of alkanes are the isomers of alkane which are formed when carbon-carbon bond get rotated. The carbon-carbon single bond gets rotated with forming different structures and these structures are studied in the conformations of alkanes. The three-dimensional structure can be easily drawn using the conformations of alkanes.

This is why the Newman projection is useful but it takes some getting used to. It is an odd point of view looking down the end of a bond, and so it is very easy to add or lose carbons.

A compound must have at least two chiral centres to have diastereomers. Let's look at a Compound "A" with two chiral centres. "C2" and "C3" are chiral centres. If we change the configuration at "C2", we get Compound "B". This is not a mirror image of "A", nor is it superimposable with "A". It is a diastereomer of "A".
