Concept explainers
(a)
Interpretation:
The aldopentoses which are enantiomers out of the eight aldopentoses are to be stated.
Concept Introduction:
Enantiomers are the pairs which are mirror images of each other. These mirror images are non-superimposable to each other. This means the forms of a compound which exists in two non-superimposable forms each of which is a mirror image of other form is known as enantiomers.
(b)
Interpretation:
The aldopentoses which are C-2 epimers out of the eight aldopentoses are to be stated.
Concept Introduction:
C-2 epimers are the compounds which has different configuration at second carbon atom and have same configuration at all other carbon atoms.
The stereogenic center present in the compound which makes the orientation of molecules different is known as epimers.
(c)
Interpretation:
The aldopentoses which forms an optically active compound on oxidation with nitric acid is to be stated.
Concept introduction:
Aldopentoses are the compounds containing five carbon atoms and one
