Document Summary
1500 when have benzene rings also have regions of benzene . called overtones existence. All c=c for benzene ring these random peaks suggest. H ( h - bond ) . see a bunch of different peaks that are overlapping to make a broad peak . The true structure is the resonance hybrid , with the most stable structure weighing more. Water on your sample , it can interfere. Four peaks overtone are qharactenistic of benzene rings . mononebstituted. The fingerprint region has too many peaks to be able to discern much . Carbonyls are relatively easy to pick out due to the massive peak at. The difference between both molecules is a double bond . Functional group ( ketone shifting it to a slightly lower wavelength due to resonance e. 9 single bond character the presence of a resonance contributor weakens the due to the former. The single bond character results in absorption at a lower frequency.
