Question
Which of the following is true about the area under each signal in a 1H NMR spectrum?Select answer from the options belowIt indicates the number of protons giving rise to the signal.It indicates the number of neighboring protons. It indicates the electronic environment of neighboring protons. It indicates the number of different protons.
Solution
The correct answer is: It indicates the number of protons giving rise to the signal.
In a 1H NMR (Nuclear Magnetic Resonance) spectrum, the area under each signal (also known as the integral) is proportional to the number of protons that give rise to that signal. This is because each proton in a molecule will resonate at a specific frequency in the magnetic field, producing a signal. The larger the number of identical protons, the larger the signal will be. Therefore, by measuring the area under each signal, we can determine the relative number of protons in the molecule.
