The problem is based on the concept of NMR spectroscopy of proton.
The structures of molecules can be determined by using proton NMR spectroscopy. Different molecular environment of protons is responsible for different values in NMR.
The number of NMR signal in a compound is equal to number of chemically nonequivalent protons present in that compound.
The splitting of NMR signals take place according to N+1 rule. If there are N protons present in neighboring atom then number of peaks is equal to N+1.
The structure of methyl propionate is as follow.
The number of proton adjacent to C is zero. So, number of peak for C is one. Thus, the proton signal splits into singlet.
The number of protons adjacent to A are two. So, number of peaks for A are three. Thus, the proton signal splits into triplet.
The number of protons adjacent to B are three. So, number of peaks for B are four. Thus, the proton signal splits into quartet.
By using information from step 1, step 2 and step 3 the NMR spectra for methyl propionate is as follow.
