NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

Question

Pent-1-ene and pent-1-yne are low-boiling hydrocarbons that have different
molecular ions in their mass spectra. Match each hydrocarbon to its mass
spectrum.
