The subsequent desk reveals that the intuitions from "non-polar", "polar aprotic" and "polar protic" are place numerically �?the "polar" molecules have greater amounts of δP as well as protic solvents have better levels of δH. For the reason that numerical values are employed, comparisons is often made rationally by evaluating quantities. For example, acetonitrile is a lot more polar than acetone but here reveals marginally considerably less hydrogen bonding. Solvent Chemical system δD Dispersion δP Polar δH Hydrogen bonding
