Linear Free Energy Relationships (LFERs) have long been a cornerstone of physical organic chemistry, providing a quantitative framework to relate substituent electronic effects with chemical reactivity. These relationships, particularly in the context of the Hammett equation, allow for the correlation of reaction rates and equilibria with substituent constants, providing insights into mechanistic pathways. Traditionally, these substituent constants (Hammett parameters such as σ p ) have been derived from empirical data, yet modern computational methods offer an alternative path to capture these effects. In recent work, Luchini and Paton benchmarked the correlation of various computational charge schemes and other computationally derived properties with experimental Hammett parameters. In Fig. , we employ CEH-v2 atomic charges to demonstrate its capability to predict substituent effects on reactivity in aromatic systems using the same experimental data.
