Guys…!! Looking out for something important to learn within no time..?? Here is a fast over-view of open chain reactions of Glucose which can be grasped quickly…!!
1. Reaction of glucose with phenyl hydrazine:
In the above reaction is with the given reagent first two carbons get – NHPh
2. Reaction of Glucose with Bromine Water:
Bromine water is used as an oxidizing agent.
It oxidizes aldehyde group into acidic (-COOH) group.
\(\underset{C{{H}_{2}}OH}{\overset{CHO}{\mathop{\underset{|}{\overset{|}{\mathop{{{(CHOH)}_{4}}}}}\,}}}\,\xrightarrow{B{{r}_{2}}\,\,water}\underset{Glucaric\,\,acid\,(or)\,Saccharic\,acid}{\mathop{\underset{C{{H}_{2}}OH}{\overset{COOH}{\mathop{\underset{|}{\overset{|}{\mathop{{{(CHOH)}_{4}}}}}\,}}}\,}}\,\)3. Reaction of Glucose with Hydroxyl Amine:
\(\underset{C{{H}_{2}}OH}{\overset{CHO}{\mathop{\underset{|}{\overset{|}{\mathop{{{(CHOH)}_{4}}}}}\,}}}\,\xrightarrow{N{{H}_{2}}OH}\underset{Aldoxime}{\mathop{\underset{C{{H}_{2}}OH}{\overset{CH=N-OH}{\mathop{\underset{|}{\overset{|}{\mathop{{{(CHOH)}_{4}}}}}\,}}}\,}}\,\)4. Reaction of Glucose with Hydrogen Cyanide:
5. Reaction of Glucose with Hydrazine:
6. Reaction of glucose with Reducing Agent HI + Red IP:
\(Glu\cos e\xrightarrow{HI/P}\underset{n-hexane}{\mathop{C{{H}_{3}}-{{(C{{H}_{2}})}_{4}}-C{{H}_{3}}}}\,\)HI + Red P is a strong Reducing Agent which reduces alcohol, Aldehyde, Ketone, Carboxylic acids and their derivatives in to Alkane.
