Cyclohexanone, Reagent, ACS is used as a synthetic intermediate and solvent. In cyclohexe you should see a peak from the C=C stretch around 1600 cm-1 that isn’t present in cyclohexane. Notice how strong this peak is, relative to the others on the spectrum: a strong peak in the 1650-1750 cm-1 region is a dead giveaway for the presence of a carbonyl group. If there is a very strong peak between 1640 and 1850 cm -1 , there is most likely a carbonyl function in the molecule.
Alkenes will usually show a peak to the left of 3000 as well due to the C=C-H, whereas alkanes usually only show absorption below 3000. ChemicalBook ProvideCyclohexanone(108-94-1) 1H NMR,IR2,MS,IR3,IR1,1H NMR,Raman,ESR,13C NMR,Spectrum View the Full Spectrum for FREE!

Identify which spectrum belongs to which compound and assign the bands in each spectrum to rationalize your choice. The region of the infrared spectrum from 1200 to 700 cm-1 is called the fingerprint region. MDL number MFCD00001660.
The IR Spectrum Table is a chart for use during infrared spectroscopy.The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups. There are two tables grouped by frequency range and compound class. Cyclohexanone oxime 97% CAS Number 100-64-1.
The IR spectra of cyclohexanol and cyclohexanone are shown below. This is the most important range in the entire IR spectrum for organic chemists. The IR spectra of cyclohexane includes a strong intensity of 2960-2850 of stretching absorption and a variable intensity of 1470-1350 of scissoring and bending absorption.
As an ACS grade quality reagent, its chemical specifications are the de facto standards for chemicals used in many high-purity applications and typically designate the highest quality chemical available for laboratory use. The key absorption peak in this spectrum is that from the carbonyl double bond, at 1716 cm-1 (corresponding to a wavelength of 5.86 mm, a frequency of 5.15 x 10 13 Hz, and a Δ E value of 4.91 kcal/mol). Figure 2. Cyclohexanone is occasionally found as a volatile component of human urine. Cyclohexanone, Technical is an organic compound and oil, and most often a precursor to nylon. Biological fluids such as blood and urine have been shown to contain a large number of components, some of them volatiles (low boiling point) apparently present in all individuals, while others such are much more variable. The IR spectra of cyclohexanol and cyclohexanone are shown below. Cyclohexanone View entire compound with free spectra: 27 NMR, 11 FTIR, and 1 Raman.
The molecular formula for cyclohexane is C6H12, and the spectrum corresponds to the functional class of bonds in alkanes, CH2.
