Which of the following compounds are appropriately classified as polar aprotic solvents? — Reaction Mechanism Chemistry Question

💡 Solution & Explanation

Polar aprotic solvents possess a dipole moment but lack an acidic hydrogen atom capable of hydrogen bonding. Acetone, DMSO, and DMF fit this criterion. Formamide ($HCONH_2$) contains N-H bonds, meaning it possesses acidic hydrogens and is therefore a polar protic solvent.
