Scheme Of glucose
Physical Characters :-
1. Condition → solid ,crystalline,microcrystalline
2. Color → white
3. Odor → odorless
4. Miscibility :
- H2O → soluble
- Litmus Paper → no change Comment : neutral compound
- Anhydrous CuSO4 → Comment :
General Reactions :-
1. Dry Heat :
- Change in appearance → melt,boil, swelling ,charring
- Degree Of Inflammability → inflammable , Non-Smoky So it maybe : Lower aliphatic comp.
- Nitration Test → Not applied
- Odor produced → burnt sugar odor comment:- May be carbohydrates or hydroxy aliphatic acid or its salt
- Residual Ash → present +conc HCl → no eff. Comment : Non me tallic comp.
2. Action Of Sodalime →
-on cold No Characteristic Observation
-on hot burnt sugar odor Comment :-It may be carbohydrate or hydroxy aliphatic acid
3. Action Of 30% NaOH →
-on cold :No Characteristic Observation
-on hot :brown solution +carmel odor ((carmelization))Comment :-May be carbohydrate except starch and sucrose
4. Action Of NaHCO3 → No effervescence Comment : Not strong acidic compound
5. Action Of FeCl3 → No Characteristic Observation
6. Action Of C.H2SO4 → Charring + effervescence on hot comment :It may be carbohydrate or tartaric acid or its salt
7. Element test : X ( absent ) N( absent ) S( absent )
Special Tests :-
1-molish's test:-sample solution +alcoholic alpha napthol shake well then add coc H2SO4 on the wall of tube withOUT shacking →aviolet ring
2-slwanof's test
sample(solid)+resorcinol +conc HCl→heat in water bath →light or no red color
