We further investigate the implicitly learned solvent properties to gain some chemical insights to derive general conclusions on the preferred solvent properties that can result in a high reaction rate for the Menschutkin reaction. In Fig. , we plot each solvent in relative-rank order, with x and y axis indicating n 2 and log ε, respectively. B is represented by the size of each bubble whose scales are shown in the legend. The relative ranks are indicated using a colorbar, with the top-10 and last-10 ranked solvents also denoted with texts for clarity. Upon examination of Fig. , it seems that the dielectric constant emerges as the predominant factor influencing reaction kinetics. This finding aligns with the established results for the Menschutkin reaction, where polar aprotic solvents are typically favored 101,102 . Also, in scenarios where differences in dielectric constants are small, a higher refractive index tends to correlate with higher reaction rates. Among the top-ranked solvents, there exists a notable uniformity in basicity levels, while no clear trend can be observed for basicity across all identified solvents, which is also consistent with the PDP plot for B (see Fig. ).
