Cyclohexane frequency

WebIt is [possible] to distinguish cyclohexane and cyclohexene by IR spectroscopy. The =C-H stretch should appear in the spectrum of [only cyclohexene] around [3000‑3100] cm-1, which will be probably easier to see than the corresponding C=C around [1600‑1680] cm-1. When using NaCl or KBr plates for an experiment, make sure to avoid The 6-vertex edge ring does not conform to the shape of a perfect hexagon. The conformation of a flat 2D planar hexagon has considerable angle strain because its bonds are not 109.5 degrees; the torsional strain would also be considerable because all of the bonds would be eclipsed bonds. Therefore, to reduce torsional strain, cyclohexane adopts a three-dimensional structure known as the chair conformation, which rapidly interconvert at room temperature via a process known as a chair …
