Consider a fluorine radical generating a radical from butane. Predict whether the transition state is reactant-like or product-like and justify your answer. Use the the following bond-dissociation enthalpies.

• A. Since the reaction is endothermic, the transition-state is reactant-like.
• B. Since the reaction is endothermic, the transition state is product-like.
• C. Since the reaction is exothermic, the transition-state is reactant-like.
• D. Since the reaction is exothermic, the transition-state is product-like.

Answer: (C)
