Analyze the peaks in this NMR spectrum of p-nitrophenol
assigning the peaks, discuss multiplicity, splitting,
shielding/deshielding effects, and integration.
I have assigned the peaks but i am not sure if i have done it
correctly. Is there expected to a peak for the -OH? or is there not
a peak because the proton is exchangeable? is there complex or
normal splitting observed?

What is the structure of the unknown compound?
It
is probably 4-heptanone
the only thing that doesn't match is m/z=27 in mass spectrum.
right?
