What is the chemical equation for the reaction between glucose and Benedict's reagent?

Answer 1

.H-C=O + 4OH- + 2Cu2+ --> HO-C=O + Cu2O(s) + 2H2O

.H-C-OH....................................H-C-OH

HOC-H ....................................HOC-H

.H-C-OH....................................H-C-OH

.H-C-OH....................................H-C-OH

H2C-OH....................................H2C-OH

[Dots were used ..... to fill up spaces because repeating space bar will not work as space holder for vertical Fischer projection]

[Benedict's reagent will work out as Cu2+ in hydroxidic (OH-) solution]

Answer 2

CHO

(CHOH)4 + Na3C6H5O7 + Na2CO3 + H2O + CuSO4

CH2OH

gives reddish ppt in water due to formation of Cu2O

Answer 3

The reaction between lactose and benedict's reagent is it reduces copper sulfate to copper. However, it also turns the solution red.
