Question

cyclopropane react with hydrogen in presence of Ni catalyst why?​

Answer 1

Cyclopropane reacts with hydrogen in presence of Ni catalyst because it is an unsaturated compound.

• In organic chemistry, an unsaturated compound is the one with π bonds (double/triple bonds).
• Saturated compounds only have sigma bonds in them.
• Unsaturated compounds can undergo catalytic hydrogenation to form saturated compounds.
• The above reaction is as follows:

         C₃H₆ + H₂  --> C₃H₈ (Propane)

• The above reaction is a reduction reaction since hydrogen is added to the reactant.

Answer 2

Cyclopropane react with hydrogen in presence of Ni catalyst is a Hydrogenation reaction

Explanation:

• In hydrogenation reaction takes place between the hydrocarbon compound and hydrogen molecule $(H2)$ .
• Here the reaction takes place in the presence of nickel, palladium or platinum.
• The process is generally used to reduce the organic compound.
• Hydrogenation reaction involves the addition of pairs of hydrogen atoms to a molecule usually it is an alkene.
• The catalyst used for the reaction is usable.
• In a noncatalytic reaction, hydrogenation takes place at a high temperature.
• Hydrogenation reaction helps to reduce the double and triple bonds in hydrocarbon.
