Vedclass · Answer

(B) The reaction of glucose with phenylhydrazine involves the formation of glucosazone. In this reaction,one molecule of glucose reacts with $3$ molecules of phenylhydrazine. The first molecule of phenylhydrazine reacts with the aldehyde group to form a phenylhydrazone. The second and third molecules of phenylhydrazine are involved in the oxidation and subsequent formation of the osazone structure at the $C-2$ position. Therefore,the value of $X$ is $3$.

$A$ glucose molecule reacts with $X$ number of molecules of phenylhydrazine to yield osazone. The value of $X$ is
