Question
Natural glucose is termed $$D$$ - glucose because :
A.
$$ - OH$$ on the second carbon is on the right side in Fischer projection
B.
$$ - OH$$ on the sixth carbon is on the right side in Fischer projection.
C.
$$ - OH$$ on the fifth carbon is on the right side in Fischer projection.
D.
It is dextrorotatory.
Answer :
$$ - OH$$ on the fifth carbon is on the right side in Fischer projection.
Solution :
Fischer gave the prefix $$“D”$$ to compounds whose bottom chiral has its $$OH$$ to the right. So natural glucose is called $$D$$ - glucose or dextrose.
Structure of $$D$$ - Glucose :
