2. All monosaccharides give Molisch's test.
3. Monosaccharides do not give iodine test.
4. All monosaccharides are reducing sugars and give a positive Fehling's, Benedict's and picric acid test.
5. Fehling's test uses a strong alkali.
6. Benedicts test takes place in a weak alkaline medium.
7. Barfoed's test is a specific test for monosaccharides.
8. Selivanoff's test is given by sugars containing a ketonic group.
9. Mucic acid test is given by galactose.
10. The osazone crystal has a characteristic shape and melting point and assists in identification of reducing sugars.
