Concept explainers
(a)
Interpretation: The relationship between and is to be stated.
Concept introduction: The anomers are cyclic monosaccharides, which differ in configuration at one stereogenic centre. These carbon atoms are called anomeric centre.
(b)
Interpretation: The relationship between and is to be stated.
Concept introduction: The anomers are cyclic monosaccharides, which differ in configuration at one stereogenic centre. These carbon atoms are called anomeric centre. The compounds which are neither mirror images nor supperimposable on each other are known as diastereomer.
(c)
Interpretation: The relationship between and is to be stated.
Concept introduction: The compounds which are mirror images as well as non-supperimposable on each other. These compounds are known as enantiomers.
(d)
Interpretation: The relationship between and is to be stated.
Concept introduction: The compounds which have same molecular formula but differ in connectivity of the substituents. These compounds are known as constitutional isomers.
(e)
Interpretation: The relationship between and is to be stated.
Concept introduction: The anomers are cyclic monosaccharides, which differ in configuration at one stereogenic centre. These carbon atoms are called anomeric centre. The compounds which are neither mirror images nor supperimposable on each other are known as diastereomer.
