Question

What are the stereochemical configurations of the two diastereomers of(2S,4R)-2,4-octanediol? (A diol is a compound with two-OH groups.)

Short answer

Diastereomers are the“non-superimposable” and “non-mirror” image compounds, e.g., all geometrical isomers

They are separated with the help of “fractional distillation and crystallization” methods.

Step-by-step solution

Step-by-Step SolutionStep 1:Diastereomers

Diastereomers are the“non-superimposable” and “non-mirror” image compounds, e.g., all geometrical isomers

They are separated with the help of “fractional distillation and crystallization” methods.

Step 2: Stereochemical configuration of Diastereomers

The diastereomers of (2S,4R)-2,4-octane diol are the pair of stereoisomers that are the non-mirror image of each other, and their overall configuration is not the same nor completely different.

The diastereomers of (2S,4R)-2,4-octane diol have the same configuration at one chiral center and a different configuration at another chiral center.

The Stereochemical configuration of diastereomers of (2S,4R)-2,4-octane diol is shown as follows:
