The strain and entropy effects of the lactone formation from ω- bromoalkane-carboxylate ions in ring sizes 3 to 23 is reevaluated. We find that ΔH((+)) is the largest contributor to the observed rates ΔG((+)) for ring sizes 3 to 6, while-T ΔS((+)) has little influence, -TΔS((+)) has more effect on the observed rates for ring sizes 8 and larger.
