We’re being asked to draw the Newman projection (viewing from C2-C3) for the most stable conformation of 2,2 dimethylbutane.


Recall conformational isomers are a class of isomers that differ in their single or σ bond rotation. Sigma bonds can freely rotate while pi bonds cannot.


The steps for drawing Newman projections are:

Step 1: Draw the bondline structure for the given molecule.

Step 2: Highlight draw an eye looking down the bond of interest.

Step 3: Draw the implied hydrogens along the bond of interest.

Step 4: Draw a front and back carbon with 3 groups each.
