Question

Which of the following statements strictly govern the principles of Heat of Hydrogenation (HOH) for alkenes?

Answer: A,C,D

💡 Solution & Explanation

Hydrogenation releases energy (exothermic). HOH increases with the number of $\pi$ bonds. For structural isomers, a more stable ground state (like trans over cis, or more substituted over less substituted) means less energy is released to reach the alkane, meaning HOH is inversely proportional to stability.
