Question

C2H4 → C2H6 → C2H4 → C2H5OH

Answer 1

C2H4 + H2 --(Ni)--> C2H6

C2H6 --(Ni, -H2)--> C2H4 + H2

C2H4 + H2O --> C2H5OH

Answer 2

The chemical reactions you've provided represent a series of transformations involving hydrocarbons. Let's go through each step:

1. C2H4 → C2H6: In this reaction, ethene (C2H4) undergoes a hydrogenation reaction, where it reacts with hydrogen gas (H2) in the presence of a catalyst to form ethane (C2H6). The reaction can be represented as follows:

C2H4 + H2 → C2H6

2. C2H6 → C2H4: This reaction is a dehydrogenation reaction. Ethane (C2H6) loses hydrogen to form ethene (C2H4). The reaction can be represented as follows:

C2H6 → C2H4 + H2

3. C2H4 → C2H5OH: This reaction is an example of a hydroxylation reaction. Ethene (C2H4) reacts with a hydroxyl group (-OH) to form ethanol (C2H5OH). The reaction can be represented as follows:

C2H4 + OH → C2H5OH

So, the overall process can be summarized as follows:

C2H4 → C2H6 → C2H4 → C2H5OH

Please note that these reactions are highly simplified representations, and in a real-world scenario, they would likely involve specific reaction conditions, catalysts, and other factors to proceed effectively.
