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
