Concept explainers
a.
To determine:
Whether the Fisher projection of pairs of carbohydrates (a.) are structural isomers, enantiomers, diastereomers, or epimers of each other.
Introduction:
When two isomeric molecules have similar molecular formula and same sequence of bonded atoms but differ in spatial orientations of their atoms, they are known as stereoisomers. The number of stereoisomer of a compound increases with the increase in chiral center of a molecule.
Structural isomers are those in which molecules have the same molecular formula but differ in the sequence of bonded atoms.
When a carbon atom is attached to four different atoms it is known as a chiral center. A compound is having only one chiral center can occur in two different arrangements called enantiomers. Molecules that are mirror images of each are enantiomers. Diastereomers are those stereoisomers who differ in orientation of more than one chiral center due to which the isomers are not the mirror images of each other. Epimers are those diastereomers which differ in only one chiral center arrangement.
