Q: Which one among the following is an example of aprotic solvent?
  • A. Toluene
  • B. Sulphuric acid
  • C. Acetic acid
  • D. Water
Correct Answer: Option A - Solvents which are incapable of acting as a proton donor are called aprotic solvents. They have no charge. Ex.– C₆H₆, CS₂, CC₁₄, DMSO, DMF, Toluene, Acetone etc. • Polar aprotic solvents are the polar solvents that have hydrogen on them but they do not have O-H or N-H bonds and therefore do not have hydrogen bonding in them. Ex.- DMF, DMSO, crown ether etc. • Polar protic solvents : H₂O, ROH, RCOOH, RNH₂, Acetic acid, Sulphuric acid, Formic acid, HF, HCl, Methanol etc.
