Chemical Product An aldehyde, butanal, CH 3 CH 2 CH 2 CH(=O), the a carbonyl containing compound with the obvious C=O stretch in the middle of the spectra at 1731 cm-1 (a little higher than the simple ketone shown above). Carboxylic acids, such as butanoic acid, CH 3 CH 2 CH 2 CO 2 H, contain both C=O (1712 cm-1) and OH groups (near 3000 cm-1). All rights reserved.

Y 4 E As before, there are also hydrogens on linear carbons, although they are much less common than tetrahedral or trigonal carbons. within these two halves of the spectrum, electronegative atoms attached to the same carbon as a proton will draw that proton downfield.

O (H b) The chemical shift of the -CH- group … The trends here are exactly the same as in carbon spectra. Figure NMR13. Structure 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. 1H Nuclear Magnetic Resonance (NMR) Chemical Shifts of Butyraldehyde with properties. http://spectrabase.com/spectrum/6e1DsTh23h3
