(B) When glucose reacts with an excess of phenylhydrazine $(C_6H_5NHNH_2)$,it forms a crystalline derivative known as glucosazone. The reaction involves the oxidation of the $C-2$ carbon and the formation of a hydrazone linkage. The overall reaction is: $C_6H_{12}O_6 + 3C_6H_5NHNH_2 \rightarrow C_{18}H_{22}N_4O_4 + C_6H_5NH_2 + NH_3 + 2H_2O$.
