Concept explainers
a)
Interpretation:
The configuration of each of the asymmetric centers in the Fisher projection of D-glucose is to be stated.
Concept Introduction:
An asymmetric carbon atom is represented as a cross in Fisher projection. The carbon chain is kept along the vertical line. The groups attached asymmetric carbon atoms are arranged according to their configuration in Fisher projection. The enantiomers of a chiral compound can be named 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) or (S) to (R).
