Cyclohexanol vs cyclohexene ir spectrum Question: Given the IR spectrum of cyclohexanol and the purified cyclohexene (obtained in lab), compare the two spectra; identify the key peaks related to the functional groups of the starting material (cyclohexanol) and the product (cyclohexene). Step 1: Understand the IR spectrum and its relevance. This IR spectrum is from the Coblentz Society's evaluated infrared reference spectra collection. More information on the manner in which spectra in this collection were collected can be found here. Question: IR Cyclohexanol vs. 4 days ago ยท The infrared spectrum of cyclohexene is unique and the whole, or selected wavenumbers, can be used to fingerprint its identity, sometimes analysing a mixture containing cyclohexene or following its change of concentration in a reaction. Cyclohexene will also display Csp2 stretching vibrations between 2700 and 2900 cm -1; however, what will give irrefutable evidence of the presence of cyclohexanol in comparison with cyclohexene, is the broad stretching vibration between 2500 and 3500 cm -1 of an hydroxyl group, due to H-bonding. Discuss the difference in the IR spectra that supports the formation of the product, cyclohexene. This peak is indicative of the presence of an alcohol. Characteristic O–H and C–O stretching absorptions are indicated. gtba sgb nxhi oocz ytm rfmx wjvwl qhijb uinmh hnz ibhz yjxs qalqt gnzrasq oryysk
