A

I,II,III

B

II,III

C

D

III

Text Solution

Verified by Experts

The correct Answer is:
A
D and L configuration are relative configuration decided by relating structure of given saccharide with D or L glyceraldehyde.

When OH an lowest asymmetric carbon is written at right hand side, it is represented as D configuration and when OH is written on left hand side, it is represented as L configuration.

R,S-configuration is a useful tool for determination of enantiomers, diasteromers and homomers. If configuration of all chiral centers are opposite then structures are enantiomers, if all chiral centers have same configuration then they are homomers and if some have same confguration and some have opposite configuration then they are diastereomers. Among above structures find out enantiomeric structures:
