The polar character of the sulfinyl bond, which determines many of the properties of dimethyl sulfoxide (DMSO), is a result of charge transfer in low-lying π-type orbitals. This characteristica-together with the wide energy gap between the highest occupied and the lowest unoccupied molecular orbitals of this substancea-makes DMSO a relatively inert aprotic solvent with strong nucleophilicity and electrophilicity.
