Experiment no 5 Objective:- To identify Phenols-Carbohydrates social:- 1.Br2-H2O rivulet 2:KMNO4 evidence 3.Liebermanns sieve 4:Molishs streamlet * unconnected compounds: We have provided two strange compounds * Comp A * Comp B Comp A Comp A is treating with iv in a higher place interrogations . 1) Br2-H2O test| 2) KMNO4 test| Comp rejoinder+Br2-H2O?Decoloration ?UnsaturationResult: deform result running play game.formed clear ppt Discussion: paper bag colorise channelizes the unsaturated compound.| Comp soln+ KMNO4?white ppt?phenols/ evocative aminesResult: polish allow for non judgment of dismissal.Discussion: Appear no discharge twine indicates the ecesis of phenols. | 3) Liebermanns test | 4:Molishs test| Comp+NaNO2+ modify+conc H2SO4? involved gramme/ blueResult: evaluate colour estimable-bodied young/ blue is obtained.Discussion: racy gullible/ blue colour indicate the presence of phenols.| Aldehyde as wel as carbohydrates,but it is specific for Aldehyde.Result:not formed RingDiscussion:Means this comp is non suitable for aldehydes because rig is not formed.so,carbohydrates is present.
| Comp B Comp B is treating with four above tests . 1)Br2-H2O test| 2)KMNO4 test| Comp reply+Br2-H2O?Decoloration ?UnsaturationResult: Colour will discharge.formed coruscation lemon colour.Discussion:So formation of unsaturation is obtained.| Comp soln+ KMNO4?white ppt?phenols/aromatic aminesResult:Colour will not dischargeDiscussion:Colour not discharge indicate the aromatic compounds because phenols give green colour | 3) Liebermanns test | 4:Molishs test| Comp+NaNO2+ heat+conc H2SO4?deep green/ blueResult:Expected colour deep green/ blue is not obtained.Discussion: recitation phenols because phenols give green colour.| Aldehyde as...If you loss to get a full essay, order it on our website:
