검증된 단계별 안내1
Understand the definitions: A polar aprotic solvent is a solvent that has a significant dipole moment (polar) but does not have acidic hydrogen atoms (aprotic), meaning it cannot donate hydrogen bonds.
Analyze water: Water is polar and protic because it has O-H bonds that can donate hydrogen bonds, so it is not aprotic.
Analyze methanol: Methanol is also polar and protic due to its O-H group, which can donate hydrogen bonds.
Analyze acetic acid: Acetic acid is polar and protic because it contains an acidic O-H group capable of hydrogen bonding.
Identify DMSO (dimethyl sulfoxide): DMSO is polar due to the S=O bond but lacks acidic hydrogens, making it aprotic. Therefore, DMSO is a polar aprotic solvent.
