Solvents used in organic chemistry are characterized by their physical characteristics. Among the most important are whether the solvents are polar or non-polar, and whether they are protic or aprotic. Because non-polar solvents tend to be aprotic,the focus is upon polar solvents …
WebOct 4, 2024 · Methanol, ethanol, and 2-propanol -- that is, CH 3 OH, CH 3 CH 2 OH, and (CH 3) 2 CHOH -- dissolve very well in water. Butanol does not, and neither does common ether -- CH 3 CH 2 CH 2 CH 2 OH and CH 3 CH 2 OCH 2 CH 3. That comparison gives rise to a very rough rule of thumb about water solubility. WebAug 5, 2024 · EtOAc is slightly soluble in water; not infinite (as e.g. ethanol), nor this little as hexane (s). It is greener than halogenated solvents such as dichloromethane, and the boiling point higher than the for dichloromethane or diethyl ether*) is an advantage during summer. Thus, EtOAc is an often used polar solvent of extraction.
