One example is hydrogen peroxide, which reacts more effectively when heated in certain chemical reactions. Heating can accelerate the reaction by providing energy to break certain bonds in the molecules.

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. ;-)


Why do all monosaccharide react with Benedict's reagent?

because know one cares


Can Grignard reagent react with halogens?

Yes, Grignard reagents can react with halogens to form new carbon-halogen bonds. The reaction typically involves the halogenation of the Grignard reagent to yield an alkyl halide. However, care must be taken as the reaction can be slow or inefficient with certain halogens.


What is the opposite of a limiting reagent?

The opposite of a limiting reagent is an excess reagent. While a limiting reagent is the reactant that is completely consumed first in a chemical reaction, thereby determining the maximum amount of product that can be formed, the excess reagent is present in a greater quantity than needed to fully react with the limiting reagent. As a result, some of the excess reagent remains unreacted after the reaction is complete.


What are the uses of barfoed's reagent?

Barfoed's reagent is primarily used to differentiate between monosaccharides and disaccharides in carbohydrate analysis. It contains copper acetate in acetic acid, and when heated with reducing sugars, it forms a red precipitate of cuprous oxide, indicating the presence of monosaccharides. Disaccharides typically do not react under these conditions due to their more complex structure. This reagent is particularly useful in biochemical assays and food analysis to identify sugar types.

Why egg albumin and casein did not react ninhydrin reagent?

It should react to this reagent. However it must be HEATED before it will react.This is due to the fact that when Ninhydrin is heated it stabilizes and the reacts with the -NH2 groups on the amino acid.


Does simple mixing cause iron and sulfur to react?

No, they must be heated in order to react


Why biuret regent react with single amino acid?

The biuret reagent should not react with a single amino acid. The reagent reacts when there is a peptide bond linking amino acids together. If you are seeing the biuret reagent react in the presence of a single amino acid, then there must be some amino acids that are still linked together.


Does tollens reagent react with cyclohexanone?

Yes, Tollens' reagent can react with cyclohexanone. Tollens' reagent is commonly used to test for the presence of aldehydes, including cyclohexanone, by forming a silver mirror when the aldehyde is present.


Why Tollens reagent does not react with ketone?

Tollens reagent is a mild oxidizing agent that reacts with aldehydes to produce a silver mirror. Ketones, however, do not have a hydrogen atom bonded to the carbonyl group, making them resistant to oxidation by Tollens reagent. As a result, ketones do not react with Tollens reagent.


What do you call a substance to react with another element?

A "reagent" or "reactant".


Does biuret's reagent turn lavender when heated?

No, biuret's reagent typically turns violet or pink when heated, not lavender. This color change is a characteristic reaction with proteins in which the copper ions in the reagent complex with peptide bonds, forming a colored complex.


How can you make a tertiary alcohol from a grignard reagent?

you react the grignard with either an ester, an acid chloride or a ketone to get a tertiary alchohol. if you react a grignard reagent with an aldehyde you get a secondary alcohol and if you react the grignard with formaldehyde (methenal) you get a primary alchohol. same thing happens if u use R-Li instead of a grignard reagant.


Would raffinose react with benedicts reagent?

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.


Will whole milk react with benedict's reagent?

No, whole milk will not react with Benedict's reagent because milk does not contain reducing sugars like glucose or fructose, which are necessary for the reaction with Benedict's reagent to occur. Benedict's reagent is used to test for the presence of reducing sugars in a solution.
