Question
Chapter 5.16A, Problem 5.24P
Interpretation Introduction
Interpretation: The structure and mirror images of (R)-2-butyl (R,R)-tartrate and (S)-2-butyl (R,R)-tartrate are to be drawn.
Concept introduction: The enantiomers of a chiral compound can be named with the help of right hand and left hand configuration. In fisher projection, chiral carbon atom is represented by a cross. When two groups on a fisher projection are interchanged, the configuration of chiral carbon also changes from (R) to (S) aur (S) to (R).
To determine: The structure and mirror images of (R)-2-butyl (R,R)-tartrate and (S)-2-butyl (R,R)-tartrate.

To show that (R)-2-butyl (R, R)-tartrate and (S)-2-butyl (R, R)-tartrate are not enantiomers, draw and name the mirror images of these compounds.
I'm a bit confused on enantiomers, diastereomers, and then a 180 flip meaning being "the same". I know enantiomers are mirror images that can't be placed one on top of the other. I also know diastereomers are non-mirror images. Then when diastereomers are flipped 180 degrees they can be considered "the same". Why couldn't that be said for enantiomers too when flipped 180 degrees?
Thank you!
3) Your results should show that S-mandelic acid rotates light to
the right and R-mandelic acid rotates light to the left. Explain
the correlation between the R/S configuration and the direction
to which light is rotated.
4) Interpret the % ee of your unknown sample. How much of
your sample is racemic? How much of your sample is the S
enantiomer? How much of your sample is the R enantiomer?

- Assign R and S to the following molecules and state why they are enantiomers.arrow_forwardThe original definition of meso is “an achiral compound that has chiral diastereomers.” Our working definition of meso is “an achiral compound that has chiral centers (usually asymmetric carbon atoms).” The working definition is much easier to apply because we don’t have to envision all possible chiral diastereomers of the compound. Still, the working definition is not quite as complete as the original definition. See if you can construct a double allene that is achiral, although it has chiral diastereomers, and is, therefore, a meso compound under the original definition. The allene structure is not a chiral center, but it can be a chiral axis.arrow_forward1.
