Directions : (6 - 10)

Case II : Read the passage given below and answer the following questions from 6 to 10.

Carbohydrates can exist in either of two conformations, as determined by the orientation of the hydroxyl group about the asymmetric carbon farthest from the carbonyl.

By convention, a monosaccharide is said to have-D-configuration if the hydroxyl group attached to the asymmetric carbon atom adjacent to the \[-C{{H}_{2}}OH\]group is on the right hand side irrespective of the positions of the other hydroxyl groups. On the other hand, the molecule is assigned L-configuration if the \[OH\]group attached to the carbon adjacent to the \[-C{{H}_{2}}OH\]group is on the left hand side.

D-Glyceraldehyde and L-Glyceraldehyde are

A) epimers

B) enantiomers

C) anomers

D) conformational diasteriomers.
