NMR spectra: Draw the structures that match the data given in each case, and then upload your work. (a) \( \mathrm{A} \) compound with the formula \( \mathrm{C}_{7} \mathrm{H}_{14} \mathrm{O}_{2} \) has three signals in its \( { }^{1} \mathrm{H}-\mathrm{NMR} \) spectrum: a quartet at \( \delta=4.11 \) that integrates to \( 2 \mathrm{H} \), a triplet at \( \delta=1.25(3 \mathrm{H}) \) and a singlet at \( \delta=1.19 \) (9H). Draw the structure of this molecule. (b) A compound with the formula \( \mathrm{C}_{9} \mathrm{H}_{12} \mathrm{O} \) has signals in its \( { }^{1} \mathrm{H}-\mathrm{NMR} \) spectrum at \( \delta=7.03,6.75 \) and \( 6.67 \) (each a multiplet that integrates to \( 1 \mathrm{H} \), as well as singlets at \( \bar{\delta}=3.76,2.24 \) and 2.13 (each integrating to \( 3 \mathrm{H} \) ). Draw the structure of this molecule. (c) Draw the structure of Unknown \( \# 6 \) from the NMR packet \( \left(\mathrm{C}_{7} \mathrm{H}_{15} \mathrm{BrO}\right) \). Unknown #6
