WebDec 19, 2024 · Another characteristic aspect of cyclopentane [2 H 6]-3a is the magnitude of the isotope induced chemical-shifts, which are demonstrated by 19 F{1 H}-NMR. Due to the heavy atoms the two fluorine signals of [ 2 H 6 ]- 3a are shifted up-field by around 1.5 ppm and 1.1 ppm respectively compared to the protio compound 3 as shown in Figure 2 . Cyclopentane (also called C pentane) is a highly flammable alicyclic hydrocarbon with chemical formula C5H10 and CAS number 287-92-3, consisting of a ring of five carbon atoms each bonded with two hydrogen atoms above and below the plane. It occurs as a colorless liquid with a petrol-like odor. Its melting point is −94 °C and its boiling point is 49 °C. Cyclopentane is in the class of cycloalkanes, being alkanes that have one or more rings of carbon atoms.
