Draw the Newman projection of the most stable conformation of 3,3-dimethylhexane viewed through the C3—C4 bond

First, we need to draw 3,3-dimethylhexane.

3,3-dimethylhexane

Next, we need to look at carbon 3 and find all the groups it is attached to other than carbon 4 . Carbon 3 is attached to two methyl groups and an ehtyl group. Carbon 4 is attached to two hydrogens, and one ethyl group. The most stable conformation is staggered where the biggest groups on the two carbons are as far apart as possible .
