ANSWER:
Solution:
Here we have to distinguish between the following pairs of compounds in terms of H NMR spectra.
Step 1
(a) 1-bromopropane and 2-bromopropane
The difference between the NMR of 1-bromopropane and 2-bromopropane is, 1-bromopropane has three sets of signals, whereas the NMR of 2-bromopropane have only two sets of signal.
