Question
The carbonyl functional group C=0 tends to show up around 1700 cm. In truth, there is some variability in exactly where the C=0 stretch appears. Data is given below. Some are at larger values, consistent with shorter bonds. Some are at smaller values, consistent with longer bonds. O 1780 cm ¹ O H CH3 1730 cm 1 1715 cm 1 1710 cm 1 O NH₂ 1650 cm 1 1580 cm 1 • Provide the next-best resonance structure for four of the structures above. • Pick any two and state how the resonance structures can be used to help correlate structures with the given values for stretching frequencies.
