B
(water)
C
(methanol)
D
(acetonitrile)
0 Comments
Verified step by step guidance1
Understand the definitions: A polar aprotic solvent is a solvent that has a dipole moment (is polar) but does not have an acidic hydrogen (proton) that can participate in hydrogen bonding. This means it cannot donate hydrogen bonds but can accept them.
Analyze acetic acid (CH\_3COOH): It has a polar carboxyl group and an acidic hydrogen (the -OH proton), so it is polar protic, not aprotic.
Analyze water (H\_2O): Water is highly polar and has two acidic hydrogens capable of hydrogen bonding, making it a polar protic solvent.
Analyze methanol (CH\_3OH): Methanol has an -OH group with an acidic hydrogen, so it is also a polar protic solvent.
Analyze acetonitrile (CH\_3CN): Acetonitrile has a polar nitrile group (C≡N) but no acidic hydrogens, so it is polar aprotic.
