How to draw newman projections from wedge dash.
Step 1. Find the longest continuous chain of carbon atoms. There is one C atom at the centre of the circle and a second one hidden at the back of the circle. A methyl group off the back adds a third C atom. On the front carbon, the ethyl group has the longest chain, for another two C atoms. We draw a 5-carbon chain.

The four possible combination are SS, RR, SR and RS (Figure 5.6.1). One of the molecule is the enantiomer of its mirror image molecule and diasteromer of each of the other two molecule (SS is enantiomer of RR and diasteromer of RS and SR). SS's mirror image is RR and they are not superimposable, so they are enantiomers.Trick to convert wedge dash formulas into Fischer projection formulas / organic chemistryThis is why the Newman projection is useful but it takes some getting used to.
