There are 3 types of solvents commonly encountered: nonpolar, polar aprotic, and polar protic.(There ain’t such a thing as a non-polar protic solvent). 4. Nonpolar Solvents Have Little To No Dipole Moment These solvents have low dielectric constants (<5) and are not good solvents for cha...
Relaxation timeIntermolecular interactions.The density (ρ), refractive index (n_D), dielectric constant (ε_s) and relaxation time (τ) of binary mixture of allyl bromide with polar protic solvent n-butanol including those of the pure liquids, were measured over the complete composition range. ...

At a solvent-to-water ratio of 4/1 (v/v) the aprotic solvent acetonitrile gave significantly lower quantities of NVRs compared to the protic solvents methanol and ethanol. Decrease of the solvent-to-water ratio from 4/1 to 1/1 (v/v) led in case of ethanol and acetonitrile to massively...
