Which of the following solvents is classified as a polar aprotic solvent? — Reaction Mechanism Chemistry Question

💡 Solution & Explanation

Polar protic solvents possess an acidic hydrogen atom bonded to an electronegative atom (e.g., O-H or N-H bonds), allowing them to form hydrogen bonds. $NH_3$, $H_2O$, and $CH_3COOH$ are polar protic. DMSO ($CH_3SOCH_3$) is polar but lacks an acidic hydrogen, making it polar aprotic.
