Vedclass · Answer

(D) The reaction of glucose with phenylhydrazine involves the formation of an osazone derivative. One molecule of glucose reacts with $3$ molecules of phenylhydrazine $(C_6H_5NHNH_2)$. The first molecule forms a phenylhydrazone,the second molecule acts as an oxidizing agent to convert the $C-2$ hydroxyl group into a carbonyl group,and the third molecule forms the final osazone structure. Thus,the value of $X$ is $3$.

$A$ molecule of glucose reacts with $X$ molecules of phenylhydrazine to form osazone. Determine the value of $X$.
