Vedclass · Answer

(D) The reaction of glucose with phenylhydrazine proceeds in three steps:$1$. Glucose reacts with one molecule of phenylhydrazine to form phenylhydrazone.$2$. The phenylhydrazone then reacts with a second molecule of phenylhydrazine, which acts as an oxidizing agent, to form an intermediate keto-imine.$3$. Finally, this intermediate reacts with a third molecule of phenylhydrazine to form the stable osazone.Thus, a total of $3$ molecules of phenylhydrazine are required for the formation of osazone from one molecule of glucose.
