🤓 Based on our data, we think this question is relevant for Professor Cruz's class at USF.
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.
Sight down the C-2—C-3 bond, and draw Newman projection formulas for the
(a) Most stable conformation of 2,2-dimethylbutane
