Homework Answers
The number of peaks in a spectrum is equal to the number of different chemical environment protons present in the compound.
Here, benzohydrol have 3 different chemical environment protons. So it's 1H-NMR spectrum have 3 peaks.
Benzophenone have only aromatic protons.so it's spectrum have peaks at aromatic region 7-8 ppm.

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...
