(b)
Interpretation: The splitting pattern observed for each proton in the given compound is to be determined.
Concept introduction: Spectroscopy method is used to identify the structure of the molecule. It is based on the interactions between matter and electromagnetic radiations. Proton NMR spectroscopy identifies the number of hydrogen atoms present in a molecule and the nature of the functional group. The value of chemical peaks depends upon the chemical environment around the hydrogen atom.

- Please match each structure to its spectrum. The structures are at the top of the image.arrow_forwardThe proton with the lowest delta value (the most shielded) is:The proton with the highest delta value (the most deshielded) is:arrow_forwardSpectrum 2. Match the correct compound to the given NMR spectra. On the spectrum, match the signals on the NMR with the protons of the structure (use arrows to point or use letter or number designations).arrow_forward
