WebCatalytic hydrogenation is a technique that can reduce compounds by a simple experimental procedure. Catalytic hydrogenation is also known as catalytic reduction. Catalytic hydrogenation is a method of reacting with hydrogen (H2). Catalytic reduction causes hydrogen to be added to the compound, and the molecule’s shape is changed. In … WebBenzene reacts with Hydrogen in the presence of a catalyst such as Rhodium, platinum, or Raney Nickel to form Cyclohexane. In the reaction, 3 moles of hydrogen is added to the double bonds to yield saturation. The reaction is: Hence, Benzene reacts with H 2 in presence of Ni at 2000C to give Cyclohexane.
