Concept explainers
(a)
Interpretation:
From given monosaccharides, the two which are stereoisomers needs to be identified.
Concept introduction:
Stereoisomers are the molecules which have the same molecular formula and the constitution of the bonding atoms, but differ in the three-dimensional orientation.
(b)
Interpretation:
Constitutional isomeric pairs should be selected among D, E & F.
Concept introduction:
Constitutional isomers show differences in the connectivity of atoms, while they have the same molecular formula.
(c)
Interpretation:
Required changes should be done to F, in order to derive the enantiomer of F.
Concept introduction:
Enantiomers are two stereoisomers that are mirror image of each other.
(d)
Interpretation:
A Fischer projection should be derived by making necessary structural changes to D.
Concept introduction:
Fischer projection is the 2 dimensional representation of a chemical structure with horizontal & vertical lines.
