question 14

Multiple Choice

Indicate how ¹H NMR spectroscopy can be used to distinguish between the following sets of structures.

• A) The spin-spin splitting for the protons on the carbon next to the halogen will be different.
• B) The chemical shift of the resonance for the protons on the carbon attached to the chlorine atom will be shifted downfield relative to the protons on the carbon attached to the bromine atom.
• C) The chemical shift of the resonance for the protons on the carbon attached to the chlorine atom will be shifted upfield relative to the protons on the carbon attached to the bromine atom.
• D) The integration of the protons on the carbon next to the halogen will be different.
