In the Quantum Chemical Workflow section, we determine the empirical values a and b in Equation 2. For each set of C-H sites in a molecule, we extract computed Δ𝐺 • 𝑚𝑖𝑛 and fit it against experimental hydricities, obtaining an MAE of 4.43 kcal/mol and RMSE of 5.45 kcal/mol (see Figure ). We convert all computed Δ𝐺 • values into QM computed hydricities (740 compounds; 3278 hydricities) using the derived linear regression. Outliers with differences above 6 kcal/mol (10/35 compounds) are primarily anthracene derivatives (7/10) and benzyl C-H bonds (9/10), suggesting potential systematic errors in QM computations or experimental measurements. Refer to section 2 in the Supporting Information for more details. Radical and cation stability generally follows the trend: tertiary > secondary > primary » methyl carbon stability. Our study also explores the correlation between hydricities and bond dissociation energies (BDEs). Using the ALFABET model developed by Paton and coworkers to predict BDEs , we find that our QM computed hydricities exhibit a better correlation with experimental data compared to BDEs, with an MAE of 7.58 kcal/mol and an RMSE of 9.44 kcal/mol, see Fig-
