उत्तर
Glucose forms glucoxime by reaction with hydroxylamine:
\[\begin{array}{cc}
\phantom{}\ce{CHO}\phantom{.............}\ce{CH = N - OH}\phantom{.}\\
\phantom{.}|\phantom{..................}|\phantom{...............}\\
\ce{(CHOH)4 ->[NH2 - OH](CHOH)4 + H2O}\\
\phantom{}|\phantom{..................}|\phantom{..............}\\
\phantom{}\ce{\underset{\text{Glucose}}{CH2OH} \phantom{..........}\underset{\text{Oxime}}{CH2OH}}\phantom{........}
\end{array}\]
