Concept explainers
(1)
Interpretation:
The chiral centers need to be labeled in the given molecules.
Concept introduction:
Chiral carbon is an asymmetric carbon which contains four different types of groups or atoms. Monosaccharides have one or more chiral centers except dihydroxyacetone.
(2)
Interpretation:
The given molecules need to be classified as D or L monosaccharides.
Concept introduction:
Sugar molecules can name as D or L sugars according to their most oxidized carbon at the top of the Fisher projection.
(3)
Interpretation:
The enantiomers of the given monosaccharide need to be determined.
Concept introduction:
Carbon group with four different groups attached are chiral. Those compounds and their mirror image are non −superimposable and these are called as enantiomers or optical isomers.
(4)
Interpretation:
The Fisher projection of the given monosaccharide needs to be drawn.
Concept introduction:
Fisher projection is a two dimensional representation of a three dimensional molecule.
