The statements that is true about the location of signals in a 1h nmr spectrum is option D. it indicates the electronic environment of absorbing protons.
Generally, the information about the structure of molecule can be obtained from four aspects of a typical 1H NMR spectrum:
Chemical equivalent and non-equivalent protons (total number of signals)
Chemical shift
Integration
Signal splitting
A proton is a stable subatomic particle, symbol p , H⁺, or ¹H⁺ with a positive electric charge of +1e elementary charge. Its mass is slightly less than that of a neutron and the proton-to-electron mass ratio makes it 1836 times the mass of an electron.
Therefore, the correct answer is as given above
