To determine the lowest chemical shift you should expect to observe for a carbon that is a part of a double bond or is attached to an electronegative atom according to table 16-4. Concept introduction: If protons are adjacent to or near a carbon having electron-withdrawing group, they get deshielded and cause a downfield shift. Benzene and additional oxygen atoms can also cause such deshielding.
