The protic and aprotic solvents, distinguishing the feature. That means one dmso molecule cannot hydrogen bond to another dmso. Aprotic solvents, such as acetone and dimethyl sulfoxide (dmso), do not have hydrogen atoms bonded to an electronegative atom like oxygen or nitrogen.

Dimethyl sulfoxide (dmso) is a polar aprotic molecule that has the peculiar property of having a mildly nucleophilic sulfur and a basic oxygen.
It is used as a reagent in a.
Solvents are generally classified by the polarity and considered either polar or nonpolar as indicated by the dielectric constant. Protic solvents are those that can donate protons, while aprotic solvents are those that cannot. Some solvents are called “protic” and some are called “aprotic”. Examples include acetone (ch3coch3), dimethyl sulfoxide (dmso), and acetonitrile (ch3cn).
Dimethyl sulfoxide (dmso) is highlighted as the prototypical dipolar aprotic solvent, though this chapter presents comparisons with other dipolar aprotic solvents. However, in this case, the cp retained its overall structure after the first cycle but with a significant decrease in efficiency. Acetone, dimethyl sulfoxide (dmso), hexane, and chloroform are examples of aprotic solvents. Has a hydrogen atom bonded to the oxygen.
It does not have very positive hydrogens that can participate in hydrogen bonding.
Dmso is a solvent in which most cps are soluble; Use in organic reactions protic solvents : Dmso is classified as either protic or aprotic, depending on its ability to donate or accept protons. Dmso is a polar aprotic solvent, which means it can stabilize charged species without participating in hydrogen bonding with nucleophiles.
Due to the lack of an acidic hydrogen atom,. They are known for their ability to. In sn2 reactions, dmso enhances the.
