Question

Study the structures of `alpha-D`-(+) glucopyranose and `beta-D`(+) glucopyranose and mark the correct statement.

A. Structures I and II are enantiomers
B. Structures I and II are anomers
C. The two structures I and II differ in the configuration of `C_(1)` and `C_(4)`
D. Both the strucrtures I and II give 2,4-DNP test.

Answer 1

Correct Answer - B
Such isomers i.e., `alpha` form and `beta`-form which differ only in the configuration of the hydroxyl group of C-1 , are called anomers.
