![]() Pentaacetyl glucose does not react with hydroxyl amine. Glucose does not give Schiff’s test and does not react with sodium bisulphite and NH3. Other Reactions of Glucose (Presence of ring structure).Glucose and fructose gives the same osazone because the reaction takes place at C1 and C2 only. I) Glucose with phenylhydrazine to form osazone G) D – glucose with (CH 3CO) 2O and ZnCl 2 Preparation of glucose (also called dextrose, grape sugar): Epimers: Pair of optical isomers which differ in configuration around any other C atom other than C1 atom are called epimers.Examples – -D-glucopyranose and -D-glucopyranose. Anomers: Pair of optical isomers which differ in configuration only around C1 atom are called anomers.(a) Carbohydrates which on hydrolysis give large number of monosaccharide units. (a) Carbohydrates which gives 2 to 10 monosaccharide units on hydrolysis (b) It cannot be hydrolysed into simpler compounds Carbohydrates: Polyhydroxy aldehydes or polyhydroxy ketones or compounds on hydrolysis give carbohydrates.Revision Notes for Class 12 Chemistry Download as PDFĬlass 12 Quick Revision Notes for Chapter 14 Biomolecules Chemistry Revision notes in exam days is one of the best tips recommended by teachers during exam days.
