The exceptional thermodynamic stability of benzene compared to hypothetical 'cyclohexatriene' is qua — GOC and Organic Chemistry Basics Chemistry Question
Question
The exceptional thermodynamic stability of benzene compared to hypothetical 'cyclohexatriene' is quantified by a specific energy value. What is this term called?
Answer: D
💡 Solution & Explanation
The difference between the actual energy of the real molecule (resonance hybrid) and the calculated energy of the most stable hypothetical contributing canonical structure is called the resonance energy. For benzene, this is unusually large (approx. 36 kcal/mol), providing aromatic stability.
