Concept explainers
Interpretation:
The protons I-M are to be ranked in order from largest chemical shift to smallest.
Concept introduction:
A proton’s absorption peak is shifted downfield (i.e., to higher chemical shift) by nearby electronegative atoms. This downfield shift occurs because electronegative atoms are inductively electron withdrawing, so they remove electron density from the nearby proton. The proton is said to be deshielded resulting in a higher signal frequency, and thus a larger chemical shift. Magnetic anisotropy deshields hydrogen nuclei associated with simple

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) The proton with the lowest delta value (the most shielded) is The proton with the highest delta value (the most deshielded) is 2) The proton with the lowest delta value (the most shielded) is The proton with the highest delta value (the most deshielded) is Retry Entire Group 1 more group attempt remaining Submit Answerarrow_forwardI want to know if the O-H is right for the first diagram and I need help doing the rest of the problem.
