Concept explainers
Interpretation: The structure of the unknown compound by considering each spectrum individually, and then by considering all spectra together is to be stated.
Concept introduction: NMR spectroscopy is a technique used to determine a unique structure of the compounds. It identifies the carbon-hydrogen bonding of an organic compound. A hydrogen atom is called as a proton in the NMR spectroscopy.
Mass fragmentation is defined as the dissociation of unstable (energetically) molecular ions that are created in the process of making molecules go through in an ionization chamber of a mass spectrometer.
To determine: The structure of the unknown compound by considering each spectrum individually, and then by considering all spectra together.
