Solvents classification
A solvent (from the Latin solvō, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules and the most common solvent used by living things; all the ions and proteins in … See more When one substance is dissolved into another, a solution is formed. This is opposed to the situation when the compounds are insoluble like sand in water. In a solution, all of the ingredients are uniformly … See more Solvents can be broadly classified into two categories: polar and non-polar. A special case is mercury, whose solutions are known as amalgams; also, other metal solutions exist which are liquid at room temperature. Generally, the See more Fire Most organic solvents are flammable or highly flammable, depending on their volatility. Exceptions are some chlorinated solvents like See more • Free energy of solvation • Solvents are often refluxed with an appropriate desiccant prior to distillation to remove water. This may be performed prior to a chemical synthesis where water may interfere with the intended reaction See more Properties table of common solvents The solvents are grouped into nonpolar, polar aprotic, and polar protic solvents, with each group ordered by increasing polarity.

These are: polar/non-polar. protic/aprotic. These categories are important because reactions can prefer (go faster) one class of solvent over another. For example, reactions that have a charged or partially charged transition state or intermediate will go faster in polar solvents.
