butanone polarity in Thailand
[FL2 C/P #10] How is "2-butanone" more polar than "n-butanol"? I thought presence hydroxyl makes things more polar…
The ketone is absolutely more polar than the alcohol. This makes sense, right, because unlike the alcohol, the ketone has a resonance form where the oxygen atom has a formal charge. We can take a sec to look up the dipole moments on google and find that the moment for the alcohol is 1.66D, while the ketone is about 2.78D. Skarlo • 4 yr. ago
