An aprotic solvent is a solvent that lacks an acidic proton. Such solvents lack hydroxyl and amine groups. These solvents do not serve as proton donors in hydrogen bonding, although they can be proton acceptors. Many solvents, including chlorocarbons and hydrocarbons, are classifiable as aprotic, but most often "aprotic" refers to polar aprotic solvents.
