The chemical environment of protons can be deduced from their chemical shifts. What are the relative chemical shifts of the protons at the labeled positions? [Protons that are highly shielded have low delta (chemical shift) values.] 1) a The proton with the lowest delta value (the most shielded) is The proton with the highest delta value (the most deshielded) is 2) b The proton with the lowest delta value (the most shielded) is The proton with the highest delta value (the most deshielded) is

The interaction of electromagnetic radiation with the structure of molecules in the sample and their study is referred spectroscopy. Several spectroscopic methods are used to acquire sample information, and these methods are proved to be accurate, fast, …
