????
Answer
This problem is based upon the NMR spectroscopy proton.
Protone NMR spectroscopy can help determine the structures of molecules. NMR values can vary depending on the molecular environment in which protons are found.
The number of NMR signals in a compound equals the number of chemically non-equivalent protons.
N+1 rule governs the splitting of NMR signals. If N protons are present in a neighboring atom, then the number of peaks equals N+1.
Here is the structure of methyl propionate.
There is zero proton near C. The number of C peak is therefore zero. The proton signal is split into a singlet.
There are only two protons located near A. The number of protons adjacent to A is two. The proton signal is split into a triplet.
Three protons are located adjacent to B. The number of protons adjacent to B is three. The proton signal is now divided into four.
The following NMR spectra are generated using the information from steps 1 through 2.
