(b)
Interpretation: TheH1 spectra for various resonance to the hydrogen nuclei responsible for them needs to be determined.
Concept Introduction:
Spectroscopy is the method of identification of structure of the organic molecules with the help of their absorption of certain electromagnetic radiations.
The H1spectroscopy or NMR is based on the nuclear magnetic resonance of radio waves on the H atoms bonded to C atoms present in the organic molecule.
