benidict's is more sensitive because it undergoes to a series of change in color (from blue,then green to yellow and last orange) while being expose in heat.
bcoz its reagent is more stable n it doest give any false n negative result

what are the difference between these two test according to bio chemistry

benedicts test
Barfoed's solution. Glucose as a monosaccharide and a reducing sugar would react positive to Barfoed's Test. Fehlings test (Solutions A and B) tests for reducing sugars but was replaced by Benedict's as a) less hazardous and b) you don't have to mix two solutions.
yes.

After hydrolysis sucrose did give a positive test. It reduces sugar that has hemiketal and hemiaetal in it.

the tests are more simple and sensitive than Benedict's tes
Fehling test is used for reducing sugars.
yes.
Fehling's test is more sensitive than Benedict's test. It is a more reliable method for detecting reducing sugars, such as glucose and fructose, due to its two separate solutions that are mixed before use, allowing for more accurate results compared to the single solution used in Benedict's test.
I think you are referring to the test using Fehlings solution. Fehlings solution oxidises aldehydes and ketones and formic acid and is in turn reduced. The red precipitate is the copper(I) oxide formed by reduction of the copper(II) complex found in Fehlings solution. Acetic acid is not readily oxidised and so there is no precipitate. See link for more information on what the complex is in Fehlings solution and how it is prepared.

Benedict's test using Benedict's Solution.
Fehlins test is done to identify aldehides. Fehlins solution is used for this test. If aldehides are added to this soluton, a red precipitate is formed.
