Question

the singlet at 0 ppm in our proton NMR spectra

the triplet at 77 ppm in our 13C NMR spectra

the singlet at 0 ppm in our 13C NMR spectra

the singlet at 7.2 ppm in our proton NMR spectra

For 77 I know it is CDCl3 but I am not sure if it is the carbon, deuterium, or chlorine. This whole question confuses me, thank you if you can help me out. Please explain, I really want to understand this not just have answers.

the singlet at 0 ppm in our proton NMR spectra

the triplet at 77 ppm in our 13C NMR spectra

the singlet at 0 ppm in our 13C NMR spectra

the singlet at 7.2 ppm in our proton NMR spectra

the hydrogen in Si(CH3)4 the chlorine of CDCI3 the carbon in Si(CH3)4 the silicon in Si(CH3)4 the chlorine of CHCI3 the carbon of CHC13 the deuterium of CDCI3 the hydrogen of CHCI3 the carbon of CDCI3

Explanation / Answer

1) The singlet at 0 ppm in our proton NMR spectra = the hydrogen in Si(CH3)4

2) The triplet at 77 ppm in our 13C NMR spectra = the carbon in CHCl3

3) The singlet at 0 ppm in our 13C NMR spectra = the carbon in Si(CH3)4

4) The singlet at 7.2 ppm in our proton NMR spectra =  the hydrogen in CHCl3

--------In 13C NMR spectra, CDCl3 = Carbon peak appears at 82 ppm
