Question:

The incorrect statement among the following is: α-D-glucose and β-D-glucose are enantiomers. The penta acetate of glucose does not react with hydroxyl amine. α-D-glucose and β-D-glucose are anomers. Cellulose is a straight chain polysaccharide made up of only β-D-glucose units.

α-D-glucose and β-D-glucose are enantiomers.

The penta acetate of glucose does not react with hydroxyl amine.

Cellulose is a straight chain polysaccharide made up of only β-D-glucose units.

α-D-glucose and β-D-glucose are anomers.

Solution:

α-D-Glucose and β-D-glucose are anomers, not enantiomers. They have the same configuration at all chiral C atoms except the first C atom.
