ChemistrySingle correct+4 / -1Question 55 of 90

The incorrect statement among the following is :

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

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

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

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

Answer and worked solution

Official answer: B

α- and β-D-glucose differ only at C1: they are anomers (diastereomers), not mirror images, so (2) is incorrect. The other three statements are true.
