Chapter 19, Problem 19.8P

Identify the structure of a compound of molecular formula ${\text{C}}_{\text{4}}{\text{H}}_{\text{8}}{\text{O}}_{\text{2}}$ that gives the following ${}^{\text{1}}\text{H}\text{NMR}$ data: $\text{0}\text{.95}\left(\text{triplet,}\text{3H}\right)\text{,}\text{1}\text{.65}\left(\text{multiplet,}\text{2H}\right)\text{,}\text{2}\text{.30}\left(\text{triplet,}\text{2H}\right)$ and $\text{11}\text{.8}\left(\text{singlet,}\text{1H}\right)\text{ppm}$.
