The reagent which forms crystalline osazone derivative when reacted with glucose, is

A) Fehling solution

B) phenyl hydrazine

C) Benedict solution

D) hydroxyl amine

Correct Answer: B

Solution :

  \[+{{C}_{6}}{{H}_{5}}N{{H}_{2}}+N{{H}_{3}}\] Hence, phenyl hydrazine \[({{C}_{6}}{{H}_{5}}NHN{{H}_{2}})\] reacts with glucose to form osazone.
