¨ Hydrogenolysis is a reaction that involves the cleavage of a bond using hydrogen gas (H2). When an organic compound undergoes hydrogenolysis, it is typically reduced and broken down into simpler compounds, often alkanes.
¨ During hydrogenolysis, hydrogen gas reacts with a molecule, usually in the presence of a catalyst such as palladium or nickel, to break the bonds between the carbon atoms. The resulting products depend on the specific molecule being hydrogenolyzed, but in many cases, an alkane is formed. This is because the hydrogen atoms from the H2 molecule add to the carbon atoms to form a new C-H bond.
¨ For example, when benzene is hydrogenolyzed, it is reduced to cyclohexane, an alkane. The reaction can be represented by the following equation:
¨ C6H6 + 3H2 → C6H12
¨ In this case, the hydrogen gas (H2) reacts with benzene (C6H6) to form cyclohexane (C6H12), which is an alkane.
¨ Therefore, hydrogenolysis typically results in the formation of alkanes.
