Detailed explanation-1: -Principle-Anthrone test is also another general test for all carbohydrates. In this test also, carbohydrate gets dehydrated when react with conc. H2SO4 to form furfural. This furfural reacts with anthrone to give bluish green colored complex.

Detailed explanation-2: -Bial’s Test: Principle, reagents, Procedure and result Pentosses ( such as ribose sugar) form furfural in acidic medium which condense with orcinol in presence of ferric ion to give blue green colored complex which is soluble in butyl alcohol.

Detailed explanation-3: -reagent is anthranol, the enol tautomer of anthrone, which reacts by condensing with the carbohydrate furfural derivative to give a green colour in dilute and a blue colour in concentrated solutions, which is determined colorimetrically.

Detailed explanation-4: -The anthrone molecule reacts with an open-form of monosaccharide in acidic conditions to form a blue-green color complex.
