Please tell me what compounds the following IR spectrum represents and why. What's written in Spectrum is the experimental formula of the compound. 0.8 0.6 C5H80 Transmitance 0.4 0.2 3000 1000 2000 Wavenumber (cm-1)
Match up the structures with the Spectrums, (A-E), explain why you matched the structure with the spectrum (ex: a large broad signal at approximately 3500cm^-1 so you have chosen an alcohol), and give the name of the IUPAC name of the compound.
