(b)
Interpretation: The number of peaks into which each single of labeled proton will split is to be predicted.
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.

Why do both signals have the same intensities?arrow_forward
- Which carbon would have a signal farthest downfield in the 13C NMR spectrum for this molecule? d. CI H. C. a O A. a B. b OD.d E. earrow_forwardhow does the chemical shift change when a carbon is connected to an electronegative atom via double bond compared to a single bond? Is the carbon signal for a carbon in a double bond with oxygen downfield or upfield?arrow_forward[Review Topics] [References] 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) r 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 Submit Answer Retry Entire Group 9 more group attempts remainingarrow_forward
