Why should ketoses not react with benedict’s reagent? think about the type of reaction and be specific.

There's no reducing sugar.

Explanation:

The Benedict test is another of the oxidation reactions, which, as we know, helps us to recognize reducing sugars, that is, those compounds that have their free anomeric OH, such as glucose, lactose or maltose or cellobiose, in the Benedict reaction can reduce the Cu2 + that presents a blue color, in an alkaline medium, the cupric ion (given by cupric sulfate) is able to be reduced by the effect of the aldehyde group of sugar (CHO) to its Cu + form. This new ion is observed as a red brick precipitate corresponding to cuprous oxide (Cu2O), which precipitates from the alkaline solution with a red-orange color, this precipitate is considered as evidence that there is a reducing sugar.

Benedict's reagent is composed of:

*Cupric sulfate.

*Sodium citrate.

*Anhydrous sodium carbonate.

The evidence of Benedict's reaction is the formation of the precipitate Ion Cuprous (Cu2O).

It means:

Cu+2 > Cu+1

Then, if we don't have a reducing sugar, the reactive is not going to react with our sample.

explanation:

and the person below goggled it.

mark as brainliest

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
