In the following E- and Z- stereoisomers, the 'H NMR spectrum of one of the isomers consists of a quartet (2 H) at 8 2.8, a triplet (3 H) at 8 0.9, a singlet at 8 3.5 for the CH2-Br moiety and two singlets at 8 2.1 and 2.5 for the CH3 groups. Assign the values and suggest an experiment to establish which of the isomers gives rise to the spectrum 5. CHз CH3CH2...

1. Draw the 1H-NMR spectrum of 1,4-dimethoxybenzene. Clearly show the multiplicity, the relative peak heights, and integration value of each signal in the 1H NMR spectrum. Chemical shifts. 1,4-Dimethoxybenzene: 3.80 (CH3), 6.80 ppm (Ph-H). (35 points) 2. What is the absorptivity of an analyte in a concentration of 5 mM with an absorbance of 0.8 when measured with a 1-cm pathlength cuvette. (25 points)
