Concept explainers
(1)
Interpretation:
The chiral center needs to be labeled in each compound.
Concept introduction:
Chiral carbon is an asymmetric carbon which contains four different types of groups or atoms.
(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 Fischer projection.
(3)
Interpretation:
The enantiomers for the given monosaccharides need to be drawn.
Concept introduction:
Carbon group with four different group attached are chiral. Those compounds and their mirror image are non −superimposable and these are called as enantiomers or optical isomers.
(4)
Interpretation:
The Fischer projections for the given monosacchrides need to be drawn.
Concept introduction:
Fischer projection is a two dimensional representation of a three dimensional molecule.
