Explain the relative chemical shifts of the benzene ring protons in Figure
A.) How many signals are seen for the CNMR spectrum of the unknowns C6H14O? B.) Explain the chemical shifts of the signals seen based upon the location of the carbons that are relative to deshielding group if any are seen in the compound (unknown is C6H14O)? For question A. I believe it is 4 signals. For question B. I know that none of the signals are in the deshielding are of the chart but are all located in the shielded region but i am unsure of how to determine the chemical shifts of the given signal. If possible an in-depth explanation would be greatly appreciated in order to understand this better.
Pls help ASAP, thanks!"predict the multiplicity and integral of the signal corresponding to the proton(s) indicated below"
Why is it that D hydrogens have a higher chemical shift than the E hydrogens? Aren't the D hydrogens less shielded than the E hydrogens which have carbons surrounding on both sides? And less shielding means higher chemical shift required?
