Consider the following compounds

The correct statement about the compounds `(A),(B)` and `(C )` is

Options

A. `A` and `B` are epimers
B. `B` and `C`are epimers
C. `A`and`C` are diastereomers
D. `A`and`C` are identical

Answer

A

Explanation

Epimers are diasteromers that have identical configuraitons on all their asymmetric carbon atoms except which carbon`-2`. All these compounds are aldoses. Aldoses which produce the same osazone are known as epimers because only the aldehyde group and `alpha`-carbon atom are involved is osazone formation and epimeric aldoses have identical configuraitons on all their asymmetric carbon atoms except the alpha.
