Problem 14.12 Describe the appearance of the 'H NMR spectrum of each of the following compounds. How many signals would you expect to find, and into how many peaks will each signal be split? (c) CHCH,00%CH3 (d) p-Diethylbenzene Sample Solution (a) Along with the triplet-quartet pattern of the ethyl group, the NMR (a) CICH,OCH,CH (b) CH3CH2OCH3 (e) CICH2CHOCH20% 23 spectrum of this compound will contain a singlet for the two protons of the chloromethyl group Split into triplet by two protons of adjacent methylene group CICH2-O-CH2-CH3 - Singlet; no protons vicinal to these; Split into quartet by three protons of methyl group
