Question

Sik structures are given below, followed by sik IR spectra. Match each structure to its appropriate IR spectrum. Circle and label the functional groups in each structure. For each IR spectrum, mark directly on the spectrum any peaks that allow you to . structural assignment In each case, indicate whether the peak is due to a stretching or bending vibration. is assignment is worth 24 points, i.e., 4 points for correct assignment of structure AND analysis. Only 1 point per structure will be awarded if you do not justify your assignment by identifying relevant IR peaks correctly as described CH3CH2-O-C-CH-CH3 CH3(CH2)8-C-NH2 он Structure 2 Structure 1 H2C-CH-C-NHCH2NH-C-CH-CH2 Structure 3 CH3-CH-C-OH CH3-O-C-CH2"CH2" С_CH3 он Structure 4 Structure 5 Structure6
For my organic chemistry lab, we are supposed to identify all significant peaks in each of the spectrums and label each “bond” peak with its range in cm. I am really stuck and lost on this so any help would be greatly appreciated.were also supposed to provide explanations for how we know which structure is matched with each of the spectrums.
