(PDF) Solvents and Solvent Effects in Organic Chemistry. Types of solvent on the basis of proton interaction on the basis of proton interaction, solvents are of four types, (i) protophilic solvents: solvents which have greater tendency to accept protons, i.e., water, alcohol, liquid ammonia, etc. (ii) protogenic solvents: solvents which have the tendency, the effect of solvent exposure from the point of view of neurotoxicity, reproductive and maternal effects, nephrotoxicity, cancerogenicity, hepatotoxicity, chromosomal aberrations, and вђ¦.

Chemical transformations are highly sensitive toward changes in the solvation environment and solvents have long been used to control their outcome. reactions display unique performance in solvents like ionic liquids or dmso, however, isolating products from them is cumbersome and energy-consuming. here, we develop promising alternatives by constructing solvent moieties into porous вђ¦ christian reichardt solvents and solvent eв¤ects in organic chemistry solvents and solvent effects in organic chemistry...
