Benedicts reagent tests for reducing sugars, so the question is, is raffinose a reducing sugar. Raffinose is a trisaccharide made up of glucose, fructose and galactose. It is not a reducing sugar because all of its anomeric carbons are bonded, so it will not react with benedicts reagent.

Can we use a common reagent to test all compounds?
No. One reagent does not dissolve or react with all compounds. If it did, it would dissolve the bottle you placed it in.
Will whole milk react with benedict's reagent?
Yes it will turn a yellowish color, thus representing the presence of moderate simple sugars
Why does Biurets reagent react with proteins but not amino acids?
Biuret test works for any compound containing two or more of these groups: CO-NH, CO-NH2, CH2-NH2, CNH-NH2, CS-NH2. Amino acids only have one.
How does the geosphere interacts with plants?
How geosphere interacts with biosphere is that they both protect the earth like the atmosphere is the border around earth that keeps us breathing without that we would die. How they would react is that biosphere and is part of the atmosphere so would they react
What is diphenylamine test for deoxyribose for?
When adding diphenylamine to deoxyribose you will get a dark deep purple color. If you react diphenylamine with crude DNA you will get a pink-violet color. DIphenylamine test is quantitative and the darker the color the greater the concentration of DNA in the solution
How does sodium chloride react with Benedicts?
The Benedict reagent is not for sodium chloride testing.
What sugar might be present in a sweet tasting food that tests negative with the Benedicts reagent?
Sucrose. Sucrose is a disaccharide therefore does not have free electrons in the sugar to react with the Benedict reagent. Glucose has free electrons therefore shows positive with the Benedict reagent.
How does benedicts solution react with orange juice?
cock
What sugars do baker's yeast react with?
fructose, sucrose, glucose, manndose, raffinose, and maltose
Would glucose solution produce a positive Benedicts test?
No, Benedicts reagent will show positive results if the carbohydrate is a reducing sugar. You will know if it is positive if the sample will turn from blue to green then to orange when you are cooling the solution, which is the last step when you are performing the benedicts test for carbohydrates.

Why Tollens reagent does not react with ketone?
because
Does tollens reagent react with cyclohexanone?
yes!!
How is Benedicts test used to determine the glucose content of a sample of urine in blood?
Aqueous is mixed with Benedict's reagent, a solution of copper sulfate, sodium hydroxide, and tartaric acid. The mixture is heated. Carbohydrates which react with Benedict's reagent to reduce the blue copper (II) ion to form a brick red precipitate of copper (I) oxide are classified as reducing sugars.
Why is the Benedict's test is positive when water starch and HCl keep for 30mins?
benedicts test is positive when water starch and HCL keep for 30 mins because glycosidic linkages between amylose and amylopectin breaks and free ends are available to react with Benedict reagent
When Aluminum is allowed to react with the copper sulfate What is the Limiting reagent?
usually it will be copper sulfate as a limiting reagent
Why does sucrose not react to Benedicts when glucose and fructose its components do?
Fructose and glucose are joined by their glycosidic bond in such a way as to prevent the glucose isomerizing to aldehyde, or the fructose to alpha-hydroxy-ketone form. This stops it reacting to Benidict's reagent. However sucrose indirectly produces a positive result with Benedict's reagent if heated with dilute hydrochloric acid prior to the test, although after this treatment it is no longer sucrose. ;-)
