For each H labeled a-f determine which splitting we are expected to see.
Apply the n+1 rule to assign the multiplicity (splitting) of each of the protons indicated by an arrow. Possible answers include: singlet, doublet, triplet, quartet, quintet, sextet, septet, octet and nonet. A molecule with formula C_2H_gO gave the NMR peaks below. Draw its structure.^1H NMR: 2.6 ppm (quartet, 2 hydrogens) 2.1 ppm (singlet, 3 hydrogens) 1.1 ppm (triplet, 3 hydrogens)^13C NMR: 215 ppm, 36 ppm, 26 ppm, 8 ppm

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...
