What are the steps to convert Newman projections to bond line notations?
1 Answer
You look for the longest chain, then you add the substituents.
Explanation:
Here is the Newman projection of a hydrocarbon. What is its bond-line notation?
(from people.bethelks.edu)
Step 1. Find the longest continuous chain of carbon atoms.
There is one
A methyl group off the back adds a third
On the front carbon, the ethyl group has the longest chain, for another two
We draw a 5-carbon chain.

Step 2. Locate the substituents.
Let's call the terminal
Then the front carbon in the circle is
So we have a 5-carbon chain with a methyl group at

And we have our bond-line structure.
