MCQ

Glucose forms many derivatives. The derivative which will help to prove the furanose structure is

A
Acetyl
B
Benzoyl
✓
Osazone
D
Isopropylidene

✓

Answer

Correct option: C.

Osazone

c
Glucose and fructose differ in the arrangement of atoms around the $C-1$ and $C-2$ carbon. When both of them react with three molecules of phenylhydrazine, the formation of osazone crystals makes the difference between the carbon atoms in their chain and hence, in such way it helps to prove the fructose structure.
