Is CHCl3 Polar or Nonpolar? - Techiescientist

WebNOTE- The NMR solvent used was deuterated chloroform (CDCl3). Due to contamination with protonated chloroform (CHCl3), you might see a singlet peks in the 1H NMR at 7.26ppm. You should always expect to see peaks in the 13C NMR for chloroform at 77ppm. Please take possible solvent peaks into consideration when assigning peaks in the spectra.

"WebSep 20, 2024 · Does CDCl3 show up on NMR? To avoid spectra dominated by the solvent signal, most 1H NMR spectra are recorded in a deuterated solvent. However, deuteration is not “100%”, so signals for the residual protons are observed. In chloroform solvent (CDCl3), this corresponds to CHCl3, so a singlet signal is observed at 7.26 ppm.
