Question

The α- and β-forms of glucose are:
  1. isomers of D(+) glucose and L() glucose respectively
  2. anomers of glucose
  3. diastereoisomers of glucose
  4. isomers which differ in the configuration of C2
  5. isomers which differ in the configuration of C5

A
isomers which differ in the configuration of C2
B
isomers which differ in the configuration of C5
C
diastereoisomers of glucose
D
isomers of D(+) glucose and L() glucose respectively
E
anomers of glucose
Solution
Verified by Toppr

In α and β form of glucose, only the orientation of the OH group attached to the first carbon atom is different. These type of structures are called as anomers of each other.
