Homework Answers
The Benedict's test identifies reducing sugars (monosaccharide's and somedisaccharides), which have free ketone or aldehyde functional groups.
Barfoed's test is a chemical test used for detecting the presence of monosaccharides.
Seliwanoff's test is a chemical test which distinguishes between aldose and ketose sugars.
Iodine test is used only for distinguish starch from other carbohydrates.
