NMR Split Questions
Please Help!
Question 8 3 pts Recall, split is how a signal appears in the NMR. The split is determined by N+1, where N is the number of hydrogen NEXT to the signal hydrogen. For example, carbon Ais a CH3, it is next to carbon B which is a CH2. So the signal for carbon A will be a triplet (N+1;2+1 = 3, a triplet). The integration is what the signal consists of and the split is...

Interpret the 1 H NMR spectra of tatraphenylcyclopentadienone
below.
Label the different types of protons and carbons for the
compound and locate the signals for these nuclei on the spectras.
Use the chemical shift and integral ratio to help with your peak
assignments.
Beacuse of signal overlap, you may not be able to assign
individual protons/carbons in a compound to a separate signal in
the spectrum, so in these cases unsepearted peaks in the spectrum
are to be assigned to...
