QUESTION:
Problem 42SP
Use a Newman projection, about the indicated bond, to draw the most stable conformer for each compound.
(a) 3-methylpentane about the C2-C3 bond
(b) 3,3-dimethylhexane about the C3-C4 bond
ANSWER:
Answer :
Step 1
The most stable conformer for 3,3-dimethylhexane viewed along the C3−C4 bond will have two ethyl groups in anti position and gauche interactions between two methyl groups and one ethyl group.
Start by drawing the bond line notation for the compound
\
Notice that you have one ethyl group and two methyl groups attached to C3, and two hydrogens and one ethyl group attached to C4.
Start by using a Newman projection template to draw the first staggered projection
