Chapter 12C.10, Problem 25P

Propose a structure for a compound of molecular formula ${\text{C}}_{\text{7}}{\text{H}}_{\text{14}}{\text{O}}_{\text{2}}$ with an IR absorption at ${\text{1740 cm}}^{-1}$ and the following ${}^{\text{1}}\text{H}$ NMR data:

$\begin{array}{ccc}\text{Absorption}& \text{ppm}& \text{Relative area}\\ \text{singlet}& \text{1}\text{.2}& \text{9}\\ \text{triplet}& \text{1}\text{.3}& \text{3}\\ \text{quartet}& \text{4}\text{.1}& \text{2}\end{array}$
