Which cleavage takes place in hydrogenolysis
Correct answer: B. Sigma bonds
- A. Pi bonds
- B. Sigma bonds
- C. None of above
- D. Both of above
Explanation
Hydrogenolysis involves the breaking of sigma bonds. These are the single covalent bonds between atoms, and when hydrogen gas adds to one of the atoms in the bond, it causes the bond to break. Pi bonds are not directly involved in hydrogenolysis reactions, making option B the correct choice. Option A is incorrect because pi bonds are not primarily broken in hydrogenolysis. Option C is incorrect as hydrogenolysis does involve the breaking of bonds, specifically sigma bonds. Option D is incorrect because hydrogenolysis primarily involves sigma bonds, not both sigma and pi bonds.

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.
