Vedclass · Answer

(C) When glucose reacts with one equivalent of phenylhydrazine $(C_6H_5-NH.NH_2)$,it forms glucose phenylhydrazone. However,when glucose reacts with an excess of phenylhydrazine,it undergoes a series of reactions to form a di-phenylhydrazone derivative known as glucosazone. The reaction involves the oxidation of the $C-2$ carbon and the formation of a hydrazone linkage at both $C-1$ and $C-2$ positions.

What is the product formed when glucose reacts with an excess of $C_6H_5-NH.NH_2$?
