Question

$\text{α-D-glucose}$ and $\text{β-D-glucose}$ are called:

• A. Anomers
• B. Enantiomers
• C. Geometrical isomers
• D. All of these

Answer 1

The correct option is A Anomers

The α-D-glucose and β-D-glucose are isomers called anomers. The isomer having the hydroxyl group $(-OH)$ on the right is called α-D-glucose and one having the hydroxyl group $(-OH)$ on the left is called β-D-glucose. Such pairs of stereoisomers which differ in the configuration only around $C1$ atom are called anomers.
