The next table demonstrates the intuitions from "non-polar", "polar aprotic" and "polar protic" are put numerically �?the "polar" molecules have larger levels of δP plus the protic solvents have bigger amounts of δH. Because numerical values are utilized, comparisons may be created rationally by comparing quantities. Such as, acetonitrile is much more polar than acetone but exhibits slightly less hydrogen bonding. Solvent Chemical formulation δD Dispersion δP Polar δH Hydrogen bonding
