Answer 2

The reaction sequence you provided involves the transformation of ethene (C2H4) through several reactions. Let's break down each step:

1. C2H4 → C2H6: This reaction involves the addition of hydrogen (H2) to ethene (C2H4), resulting in the formation of ethane (C2H6). It is a typical example of a hydrogenation reaction where a double bond is converted into a single bond.

2. C2H6 → C2H5Cl: In this step, ethane (C2H6) reacts with chlorine (Cl2) to form ethyl chloride (C2H5Cl). This is a substitution reaction where one of the hydrogen atoms in ethane is replaced by a chlorine atom.

3. C2H5Cl → C2H5OH: Ethyl chloride (C2H5Cl) undergoes a reaction called hydrolysis, where it reacts with water (H2O) to produce ethanol (C2H5OH). The chlorine atom is replaced by a hydroxyl group (-OH) from water, resulting in the formation of an alcohol.

4. C2H5OH → C2H4: The last step involves the dehydration of ethanol (C2H5OH), where it loses a water molecule (H2O) to regenerate ethene (C2H4). Dehydration is a common process to remove water and obtain the desired product.

So, the overall reaction sequence you provided can be summarized as:

C2H4 → C2H6 (hydrogenation) C2H6 → C2H5Cl (chlorination) C2H5Cl → C2H5OH (hydrolysis) C2H5OH → C2H4 (dehydration)

Please note that each step represents a separate reaction and requires specific conditions and catalysts to proceed.
