Write the reaction equation C6H12O6- C2H5OH- CH3-CHO- CH3-COOH- CH3-COOK

Let’s compose the reaction equations in accordance with the scheme:
С6Н12О6 = 2С2Н5ОН + 2СО2 – fermentation of glucose occurs with the participation of yeast, ethyl alcohol is released;
C2H5 – OH + CuO = H3C – CHO + Cu + H2O – oxidation of ethanol when heated with copper oxide, acetaldehyde was formed;
Н3С – СНО + Ag2O = CH3COOH + 2Ag – qualitative reaction to aldehyde, while its oxidation to acetic acid occurs;
2СН3СООН + 2K = 2CH3COOK + H2 – substitutions, potassium acetate was obtained.
The given scheme of transformations confirms the connection of carbohydrates with oxygen-containing organic compounds. The reaction products are of practical importance, for example, acetic acid and its acetate salts are used in the food industry as preservatives.
