Question

Укажите вещество х в следующей цепочке превращений: крахмал-глюкоза-х-этилен

Answer 1

Х - этанол
1) (С₆H₁₀O₅)n[крахмал] + nH₂O =>  n C₆H₁₂O₆[глюкоза]
2) C₆H₁₂O₆ =>   2C₂H₅OH[этанол-Х] + 2CO₂
3)C₂H₅OH =>  CH₂=CH₂[этилен]+ H₂O

Answer 2

The Substance "X" in the Given Chain of Transformations: Starch - Glucose - X - Ethylene

To determine the substance "X" in the given chain of transformations (starch - glucose - X - ethylene), we need to understand the chemical reactions involved.

1. Starch to Glucose: Starch is a complex carbohydrate composed of glucose molecules linked together. Through a process called hydrolysis, starch can be broken down into its constituent glucose molecules. This reaction is catalyzed by enzymes called amylases.

2. Glucose to X: Without specific information about the substance "X," it is difficult to determine the exact transformation from glucose to X. Glucose is a monosaccharide, and it can undergo various chemical reactions to form different compounds. Some possibilities include: - Glucose can be oxidized to form gluconic acid or other oxidized derivatives. - Glucose can undergo fermentation to produce ethanol or other fermentation products. - Glucose can be converted into other organic compounds through various chemical reactions, such as esterification, acetylation, or glycosylation.

Without more specific information, it is not possible to determine the exact substance "X" in the given chain of transformations.

3. X to Ethylene: Similarly, without specific information about the substance "X," it is challenging to determine the transformation from X to ethylene. Ethylene is an unsaturated hydrocarbon with the chemical formula C2H4. It is commonly produced from various sources, including the cracking of hydrocarbons or the dehydration of alcohols.

In summary, the substance "X" in the given chain of transformations (starch - glucose - X - ethylene) cannot be determined without more specific information about the chemical reactions involved in the conversion of glucose to X and X to ethylene.
