Answer 2

Chemical Equation for the Given Reaction Scheme

The given reaction scheme can be represented by the following chemical equation:

C₆H₁₂O₆ → C₂H₅OH → C₂H₄ → C₂H₄Cl₂ + ... + C₂H₆

Please note that the ellipsis (...) represents additional products or reactants that may be involved in the reaction but are not specified in the given scheme.

Explanation of the Reaction Steps

1. C₆H₁₂O₆ → C₂H₅OH: This step represents the conversion of glucose (C₆H₁₂O₆) into ethanol (C₂H₅OH). This reaction is known as fermentation and is commonly used in the production of alcoholic beverages. The balanced equation for this reaction is:

C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂

The reaction is catalyzed by enzymes present in yeast or other microorganisms.

2. C₂H₅OH → C₂H₄: This step represents the dehydration of ethanol (C₂H₅OH) to form ethylene (C₂H₄). Dehydration is a process that involves the removal of water from a compound. The balanced equation for this reaction is:

C₂H₅OH → C₂H₄ + H₂O

This reaction can be carried out by heating ethanol in the presence of a catalyst, such as alumina or phosphoric acid.

3. C₂H₄ → C₂H₄Cl₂: This step represents the addition of chlorine (Cl₂) to ethylene (C₂H₄) to form 1,2-dichloroethane (C₂H₄Cl₂). This reaction is an example of an addition reaction. The balanced equation for this reaction is:

C₂H₄ + Cl₂ → C₂H₄Cl₂

The reaction is typically carried out in the presence of a catalyst, such as iron or aluminum chloride.

4. Additional Steps: The given reaction scheme indicates that there may be additional steps or products involved, but they are not specified. Without further information, it is not possible to determine the specific reactions or products beyond the formation of 1,2-dichloroethane (C₂H₄Cl₂).

Please note that the reaction scheme provided is a simplified representation, and actual reactions may involve more complex mechanisms or intermediates.
