The carbonyl functional group C=0 tends to show up around 1700 cm. In truth, thereis 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 smallervalues, consistent with longer bonds.O1780 cm ¹OHCH31730 cm 1 1715 cm 11710 cm 1ONH₂1650 cm 11580 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 helpcorrelate structures with the given values for stretching frequencies.

In the actual molecule of which this is a Lewis structure, which of the labeled distances can change? marked H-O کا unmarked A -H H List all the distances that can change. For example, suppose all the distances were measured at a certain time, and again 0.1s later. If distance A might be 50% bigger or smaller the second time, but all the other distances are certain to be the same, you should write "A". If A and B might be different the second time, but no other distances, you would write "A, B". And so on. Note for advanced students: you can assume the molecule is dissolved in an appropriate solvent at room temperature. 0.0,... You can click the "unmarked" tab to see the molecule without any of the distances marked. X

Compare these two structures. [0=C=N] [0=C—N: Determine whether the two represent resonance contributors of a single species or depict different substances. If two structures are not resonance contributors, explain why. Select the single best answer. O The two structures are resonance contributors of the same species. The two structures are not resonance contributors because they contain different numbers of electrons. The two structures are not resonance contributors because they contain different bond orders. O The two structures are not resonance contributors because they contain bond orders having integer values. The two structures are not resonance contributors because each structure is present in its most stable (lowest energy) configuration. The two structures are not resonance contributors because they have different arrangements of atoms. X Ś
