Answer 2

Given Reaction Scheme:

The given reaction scheme is as follows: CH3COONa - CH4 - C2H2 - C2H6 - C2H5Cl - C4H10 | CO2

Transformation Steps:

To perform the transformation according to the given scheme, we need to convert each compound into the next compound in the sequence. Let's go step by step:

1. CH3COONa to CH4: - The conversion of CH3COONa to CH4 involves the reduction of the carbonyl group (C=O) to a methyl group (CH3). - This reduction can be achieved by using a reducing agent such as lithium aluminum hydride (LiAlH4) or sodium borohydride (NaBH4). - The reaction can be represented as follows: ``` CH3COONa + 4H2 → CH4 + NaOH ```

2. CH4 to C2H2: - The conversion of CH4 to C2H2 involves the elimination of two hydrogen atoms from methane to form a carbon-carbon triple bond. - This process is known as dehydrogenation and can be achieved through various methods, such as thermal cracking or catalytic cracking. - The reaction can be represented as follows: ``` CH4 → C2H2 + 2H2 ```

3. C2H2 to C2H6: - The conversion of C2H2 to C2H6 involves the addition of two hydrogen atoms to the carbon-carbon triple bond to form a carbon-carbon single bond. - This process is known as hydrogenation and can be achieved by using a catalyst, such as palladium (Pd) or platinum (Pt). - The reaction can be represented as follows: ``` C2H2 + 2H2 → C2H6 ```

4. C2H6 to C2H5Cl: - The conversion of C2H6 to C2H5Cl involves the substitution of one hydrogen atom in ethane with a chlorine atom. - This process is known as chlorination and can be achieved by using a chlorine source, such as hydrogen chloride (HCl) or chlorine gas (Cl2). - The reaction can be represented as follows: ``` C2H6 + Cl2 → C2H5Cl + HCl ```

5. C2H5Cl to C4H10: - The conversion of C2H5Cl to C4H10 involves the addition of three hydrogen atoms to the carbon-chlorine bond to form a carbon-carbon single bond. - This process is known as hydrogenation and can be achieved by using a catalyst, such as palladium (Pd) or platinum (Pt). - The reaction can be represented as follows: ``` C2H5Cl + 3H2 → C4H10 ```

6. C4H10 to CO2: - The conversion of C4H10 to CO2 involves the complete combustion of butane in the presence of excess oxygen. - This process is exothermic and produces carbon dioxide (CO2) and water (H2O) as the main products. - The reaction can be represented as follows: ``` C4H10 + 13/2
