The addition of hydrogen in alkenes or alkynes in the presence of nickel at 200-300°C yields alkanes is called
Correct answer: A. Hydrogenation
- A. Hydrogenation
- B. Addition
- C. Elimination
- D. Substitution
Explanation
Hydrogenation is the correct term for the addition of hydrogen to alkenes or alkynes in the presence of a catalyst like nickel at elevated temperatures (200-300°C), which leads to the formation of alkanes. This process involves the breaking of the double or triple bond in the alkene or alkyne and the addition of hydrogen atoms. The other options are incorrect because Addition, Elimination, and Substitution reactions involve different processes that are not related to the specific addition of hydrogen in alkenes or alkynes.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
