Step-by-step solution

Molisch's test is a general test for the detection of carbohydrates. In this test, the carbohydrate is treated with Molisch's reagent (a solution of -naphthol in ethanol) followed by the slow addition of concentrated sulfuric acid down the sides of the test tube. The acid dehydrates the carbohydrate to form furfural or its derivatives, which then condense with -naphthol to form a purple or violet-colored ring at the junction of the two liquids. Answer: carbohydrates
