CDCl_3 CCl_4 CH_3 OH CH_3 OH D_2 O Which of the following is true about the number of signals in a 'H NMR spectrum? it indicates the number of neighboring protons it indicates the electronic environment of neighboring protons it indicates the number of different kinds of protons it indicates the electronic environment of absorbing protons it indicates the number of protons in the signal Which of the following is true about the location of signals in a 'H NMR spectrum? it indicates the number of neighboring protons it indicates the electronic environment of neighboring protons it indicates the number of different protons it indicates the electronic environment of absorbing protons it indicates the number of protons in the signal Which of the following is true about the area under each signal in a 'H NMR spectrum? it indicates the number of neighboring protons it indicates thExplanation / Answer
1) Ans: D) CH3OH
Most of the NMR spectra are recorded in a deuterated solvent to stay away from the spectra dominated by the solvent signal. CDCl3, CD3CN and D2O are deuterated solvents and in CCl4 has no protons so we can these solvents to record NMR.
2) Ans: C) It indicates the different kinds of protons
By looking NMR spectra we can tell how many different types of protons present in the molecule.
3) Ans: D) It indicates the electronic environment of absorbing protons
4) Ans: E) It indicates the relative number of protons in the signal
5) Ans: A) it indicates the number of neighboring protons
6) Ans: E) 5
Five different types of protons are present in the molecule so we will observe five signals.
