Study the structures of $$\alpha {\text{ - }}D{\text{ - }}\left( + \right)$$ glucopyranose and $$\beta {\text{ - }}D{\text{ - }}\left( + \right)$$ 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 structures I and II give 2, 4-$$DNP$$ test.
Answer :
Structures I and II are anomers.
Solution :
Such isomers i.e., $$\alpha $$ - form and $$\beta $$ - form which differ only in the configuration of the hydroxyl group at $$C - 1,$$ are called anomers.
