For 2,3-butanediol, there are 3 isomers; 2 are enantiomers, one is not. Use Fischer projections and draw all three. Identify stereocenters and identify them as enantiomers and the meso compound.© BrainMass Inc. brainmass.com October 9, 2019, 4:46 pm ad1c9bdddf
The meso compound can be shown with either both -OH groups on the right of the Fischer projection, or both on the left:
This solution provides a brief response, including diagrams to show the meso compound in a Fischer projection. Fischer projects are used to draw stereocenters.
