/50 If this problem is graded: patterns to look for in 'H NMR spectra when trying to determine the Peak is a 1--noneighbors Probl stru em #5. There are some to cture of a compound. For a compoun are a r example, there are a few distinct patterns that we see for methyl groups CH3 CHj is isolated R R-C-CH, (no neighbors) 10-CH3 singlet (s) R CH3 has a Peak has integration of 3 H Probably a methyl group Peak is a doublet (d) methine R C-CH neighbor Peak is a | triplet (t) methylene methyleneH--CHs neighbor Itr a peak has an integration of 6 H, it may be a pair of equivalent methyl groups. Draw a flow chart like the one above for a peak that has an integration of 2 H. This means it is probably a methylene... the multiplicity options are singlet, doublet, triplet, quartet, pente..
