Heptanal revised

Recall the revised value for the enthalpy of formation of bicyclo[4.1.0]heptane discussed in... 

The fact that the determination of diiodine complexation constants is dependent on a second unknown makes values more uncertain than the hydrogen-bond formation constants. A revision of the statistical evaluation of diiodine complexation constants obtained by the popular Benesi-Hildebrand method [53] shows [57] that the confidence interval is always much larger than previously reported. Examples of revised 95% confidence limits are (in 1 mol ) 0.32-0.40, 0.53-1.86 and 1.10-1.32 for the complexation constants of diiodine with 1-bromobutane, benzene and dioxane, respectively. However, better 95% confidence intervals can be obtained. A careful application of the Rose-Drago method to the complexation of diiodine with carbonyl bases gives [62], for example 0.53 0.04 (benzaldehyde), 1.12 0.06 (acetone), 8.1 0.7 (AA -dimethylbenzamide) and 15 0.4 (A,A-dimethylacetamide) (in 1 mol , in heptane at 25 °C).
