Describe the addition reaction of carbon compounds with its application. State the function of catalyst in this reaction. How this reaction is different from a substitution reaction?



Addition reaction involves the addition of atoms like H over double or triple bonds . This occurs in the presence of a catalyst such as nickel or palladium.

One of its applications is to convert vegetable oil (unsaturated) to vegetable ghee(saturated) and the process is known as hydrogenation since hydrogen atoms are added.

The reaction that takes place is:
