The Molisch test is a general test for carbohydrates, detecting the presence of all monosaccharides and some disaccharides through the formation of a purple ring when a carbohydrate solution is mixed with alpha-naphthol and concentrated sulfuric acid. In contrast, the Benedict test specifically identifies reducing sugars, such as glucose and fructose, which can reduce copper(II) ions to copper(I) oxide, resulting in a color change from blue to green, yellow, or red depending on the sugar concentration. Thus, while both tests indicate carbohydrate presence, the Molisch test is broader, whereas the Benedict test is specific to reducing sugars.

Viva voce for molisch test?
The Molisch test is used to detect the presence of carbohydrates in a given sample. During a viva voce for the Molisch test, you may be asked to explain the principle of the test, demonstrate how it is performed, and interpret the results obtained. Be prepared to discuss the formation of a purple ring when positive for carbohydrates due to the reaction between α-naphthol and sulfuric acid.
When did Hans Molisch die?
Hans Molisch died in 1937.
When was Hans Molisch born?
Hans Molisch was born in 1856.
Is molisch's test is specific test for glucose?
what is the name of result from molisch test
Why does glycoproteins reacts positively with Molisch reagent?
Glycoproteins give positive results for Molisch's test. This answer is true because Molisch test was a test for sugar.
What is the positive result for molisch test?
all carbohydrates show positive result to Molisch test. this is because Molisch test is used to distinguish carbohydrates from other organic compound.
Why albumin gives positive Molisch test?
Because it is a carbohydrates and molisch test will be positive in the presence of carbohydrates
What does a positive Molisch's test on an unknown substance indicate?
A positive Molisch's test result indicates the presence of carbohydrates.
Why egg albumin gives the negative result for molisch test?
Egg albumin gives a negative result for the Molisch test because it does not contain carbohydrates. The Molisch test is used to detect the presence of carbohydrates, and since egg albumin consists mainly of proteins with little to no carbohydrates, it does not react with the reagents used in the Molisch test to give a positive result.
What is the importance of Molisch's test performed on carbohydrates?
Molisch's Test is a chemical test for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid to produce an aldehyde. Its importance is that it tests the presence of carbohydrates based on their dehydration,
Why is the molisch test slower with disaccharides?
The Molisch test detects carbohydrates by breaking them down to monosaccharides. Disaccharides need to be hydrolyzed into their constituent monosaccharides before they can react with the Molisch reagent, which makes the test slower compared to monosaccharides that can react directly.
