Strong linear correlations (a) between the transition state barrier height ΔE and the total electrostatic energy difference ΔEe and (b) between the steric energy difference ΔEs and the quantum energy difference ΔEq for SN2 reactions of 59 substituted CR1R2R3F (red color) and CR1R2R3Cl (green color) systems reacting with fluorine anion investigated in this study. See discussion in detail in the text.
