Witryna9 paź 2024 · The rate of SN2 reaction is maximum when the solvent is polar aprotic such as DMSO (dimethyl sulphoxide) (CH3)2S→O. In such solvents, the nucleophile is not solvated and can freely attack the substrate. Also, the polar nature of the solvent helps in the cleavage of C−X bond where X is the leaving group. Witryna5 sty 2015 · An aprotic solvent is a solvent that has no O-H or N-H bonds. The "a" means "without", and "protic" refers to protons or hydrogen atoms. The specific meaning of aprotic is that the molecules have no H atoms on O or N. This means that the molecules cannot form H-bonds with themselves, but they may accept H-bonds from …
