Question
Which of the following is true about the number of signals in a 1H NMR spectrum?Select answer from the options belowIt indicates the electronic environment of absorbing protons. It indicates the number of different kinds of protons. It indicates the number of neighboring protons. It indicates the electronic environment of neighboring protons.
Solution
The statement "It indicates the number of different kinds of protons." is true about the number of signals in a 1H NMR spectrum.
In 1H NMR spectroscopy, each signal represents a set of equivalent protons, i.e., protons that are in the same chemical environment. Therefore, the number of signals in the spectrum indicates the number of different types of protons present in the molecule.
The other options are not correct. The number of signals does not directly indicate the electronic environment of absorbing protons, the number of neighboring protons, or the electronic environment of neighboring protons.
