A) glucosazone
B) glucose phenyl hydrazine
C) glucose oxime
D) sorbitol
Correct Answer: A
Solution :
Glucose react with 3 molecules of phenyl hydrazine and form glucosazone. \[\underset{\begin{align} & | \\ & CHOH \\ & | \\ & {{(CHOH)}_{3}}+3{{C}_{6}}{{H}_{5}}NH\cdot N{{H}_{2}}\xrightarrow{{}} \\ & | \\ & C{{H}_{2}}OH \\ & \text{glucose} \\ \end{align}}{\mathop{CHO}}\,\] \[\underset{\begin{align} & | \\ & C=N\cdot NH{{C}_{6}}{{H}_{5}} \\ & | \\ & {{(CHOH)}_{3}} \\ & | \\ & C{{H}_{2}}OH \\ & \text{glucosazone} \\ \end{align}}{\mathop{C}}\,H=N\cdot NH{{C}_{6}}{{H}_{5}}\]
