splitting patterns lastly let’s discuss Splitting Patterns Lastly, let's discuss why some signals are comprised of only a single peak, called a singlet, while other signals exhibit splitting, and may appear as a doublet, triplet, quartet, quintet, sextet, septet, octet, nonet, etc. Splitting is due to neighboring H's. That is, H's that are separated by 3 covalent bonds are called "neighbors". Each neighbor splits a signal, and the pattern observed matches the N+1 rule: the number of peaks observed is...

Based on the splitting pattern, how many total protons are coupled to the proton that gave rise to the signal shown here? Chemical shift (ppm)
For each peak of the NMR, describe the chemical shift, functional group, integration, splitting pattern, neighbors, the molecule that the peak represents, and finally draw the final structure of the NMR. 6H, Doublet
