Hi, my lecturer started teaching this course just calling notes out nothing makes sense to me and the rest of my class. he gave this question to try can you please me understand this.. the Atkins does help me either. i dont know anything about assigning peaks and coupling , spin spin etc . This course has a high failure rate and i dont want to be a statistic please explain this to me
question is

Below is the 1H NMR spectrum of 1-nitropropane and of chloroethene (spectrometer
operating frequency 200 MHz).
(i) Measure the chemical shifts (in ppm) and spin-spin coupling(s) (in Hz).
(ii) Assign the peaks in the spectrum to protons in the sample using information about
the chemical shifts.
(iii) Assign the peaks based on the spin-spin coupling patterns (and the signal
intensities for nitropropane).
