# A fast overview of open chain reactions of Glucose

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:

$$\underset{(Glu\cos e)}{\mathop{\underset{C{{H}_{2}}OH}{\overset{H-C=O}{\mathop{\underset{|}{\overset{|}{\mathop{{{(CHOH)}_{4}}}}}\,}}}\,}}\,\xrightarrow[(Hydrozine)]{N{{H}_{2}}N{{H}_{2}}}\underset{(Hydrazone)}{\mathop{\underset{C{{H}_{2}}OH}{\overset{H-C=N{{H}_{2}}}{\mathop{\underset{|}{\overset{|}{\mathop{{{(CHOH)}_{4}}}}}\,}}}\,}}\,$$

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.
