The conversion of benzene into cyclohexane is a/an:
Correct answer: A. Exothermic process
- A. Exothermic process
- B. Isothermic process
- C. Endothermic process
- D. Both A and B
Explanation
This reaction is the hydrogenation of benzene. It involves breaking three pi bonds and forming six new and stronger C-H sigma bonds. The formation of these stronger bonds releases a significant amount of energy (ΔΗ = -208 kJ/mol), making the process exothermic.

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.
