Question

Which of the following is true about the number of signals in a 1H NMR spectrum?

18. How many signals would you expect in the 1H NMR spectrum of the compound shown below? A) 4 B) 5 C) 6 D)7 E) 8 17. Which of the following is true about the number of signals in a 1H NMR spectrum? A) It indicates the number of protons in the signal. B) It indicates the number of different kinds of protons. C) It indicates the electronic environment of absorbing protons. D) It indicates the electronic environment of neighboring protons. E) It indicates the number of neighboring protons.

Explanation / Answer

18) The number of signals for this molecule will be eqaul to 7 (The correct option is Option D)

- Since there are 7 different kinds of proton available in this molecule, hence the number of signals or peaks generated in the H-NMR spectrum

17) The correct answer is "It indicates the number of different kinds of protons"

(The correct option is Option B)

-- It is the basic defintion of signals in H-NMR (no explanation can be provided)
