Question

3) Analyze the following IR spectra and match each spectrum to the correct molecule using the list of molecules (only one structure for each molecule; not all molecules will be used). Draw the correct molecule in the box to the right. Label the relevant peaks in the spectra with the proper functional group. If the absence of key peaks led to your choice, indicate which key peaks were absent. Transmittance (%) 4000 3000 2000 1500 1000 500 Wavenumber (cm-1)

Step 1

Step 1:** Identify key peaks in the IR spectrum: - Peak at 2100 cm^-1: indicates a carbon-carbon triple bond - Strong peak around 3300-3400 cm^-1: indicates terminal alkene (RCH=CH2) - Sp3 carbon-hydrogen peaks around 2900 cm^-1 ** Show more…
