As before, there are also hydrogens on linear carbons, although they are much less common than tetrahedral or trigonal carbons. 5.1.5 Alcohol oxidation sequences. Free, fast text access to hundreds of thousands of NMR, IR, Raman, UV-Vis, and Mass Spectra. Alcohols can be readily oxidised to aldehydes and ketones and aldehydes are easily oxidised further to carboxylic acids. Hydrogens attached to carbon adjacent to the sp 2 hybridized carbon in aldehydes and ketones usually show up 2.0-2.5 ppm.. Aldehyde hydrogens are highly deshielded and appear far downfield as 9-10 ppm. Fast and Accurate Algorithm for the Simulation of NMR spectra of Large Spin Systems.
