Vedclass · Answer

(B) Glucose reacts with excess phenylhydrazine $(C_6H_5NHNH_2)$ to form glucosazone,which is a crystalline osazone derivative.This reaction involves the oxidation of the $C-2$ carbon and the formation of a hydrazone linkage at both $C-1$ and $C-2$ positions.The chemical equation is: $CHO(CHOH)_4CH_2OH + 3C_6H_5NHNH_2 \rightarrow C_6H_{10}O_4(NNHC_6H_5)_2 + C_6H_5NH_2 + NH_3 + 2H_2O$.
