WebComparing t he infrared, mass, 1H NMR and 13C NMR spectra of the 4 halogenoalkane isomers of C 4 H 9 Cl. NOTE: The images are linked to their original detailed spectral analysis pages AND can be doubled in size with touch screens to increase the definition to the original 1-chlorobutane, 2-chlorobutane, 1-chloro-2-methylpropane and 2-chloro-2 … WebDec 31, 2024 · Each of these is likely to split to produce ions with a positive charge on the CO group. In the pentan-2-one case, there are two different ions like this: [CH 3 CO] + [COCH 2 CH 2 CH 3] + That would give you strong lines at m/z = 43 and 71. With pentan-3-one, you would only get one ion of this kind: [CH 3 CH 2 CO] +

WebThe molecular ion peaks (M+ and M+2) each contain one chlorine atom - but the chlorine can be either of the two chlorine isotopes, 35 Cl and 37 Cl. The molecular ion containing the 35 Cl isotope has a relative formula … WebThe line at m/z = 29 is typical of an ethyl ion, [CH 3 CH 2] +: The other lines in the mass spectrum are more difficult to explain. For example, lines with m/z values 1 or 2 less than … WebBecause there are two abundant isotopes of both chlorine (about 75% 35 Cl and 25% 37 Cl) and bromine (about 50% 79 Br and 50% 81 Br), chlorinated and brominated compounds have very large and recognizable M+2 peaks. Fragments containing both isotopes of Br can be seen in the mass spectrum of ethyl bromide: brownsea island swim 2022
