2,3,4,5-hexane tetra-ol numbering
« on: October 28, 2020, 05:23:18 PM »
Suppose one is looking at stereoisomers of this compound.  How does one pick which carbon is carbon-1?  Does it depend on the absolute configuration of carbon 2?  In other words do we pick the numbering system on the basis of the R or S configuration of carbon-2?  I am helping a student with an assignment on Fischer projections, and this question came up?

Use the convention used in the nomenclature R, S - alphabetical order: 2D before 2L.
