The incorrect statement among the following is:a)α-D-glucose and...
Explanation:
Enantiomers:
Enantiomers are molecules that are mirror images of each other but cannot be superimposed onto each other. In the case of α-D-glucose and β-D-glucose, they are not enantiomers because they are not mirror images of each other.
Anomers:
Anomers are a type of diastereomers that differ in the configuration of the anomeric carbon. α-D-glucose and β-D-glucose are indeed anomers of each other because they differ in the configuration of the hydroxyl group at the anomeric carbon.
Cellulose:
Cellulose is a straight-chain polysaccharide composed of β-D-glucose units linked together by β-1,4-glycosidic bonds. It is not made up of α-D-glucose units.
Penta acetate of glucose:
The penta acetate of glucose is a derivative of glucose that has all five hydroxyl groups acetylated. This compound does react with hydroxylamine to form an oxime derivative.
Therefore, the incorrect statement among the options provided is:
α-D-glucose and β-D-glucose are enantiomers (Option B).
Enantiomers:
Enantiomers are molecules that are mirror images of each other but cannot be superimposed onto each other. In the case of α-D-glucose and β-D-glucose, they are not enantiomers because they are not mirror images of each other.
