Chapter 21, Problem 21.10P

Draw the structure of all constitutional isomers that contain a ketone and have molecular formula ${\text{C}}_{\text{5}}{\text{H}}_{\text{10}}\text{O}$. Give the IUPAC name for each isomer and state how ${}^{13}\text{C}\text{NMR}$ spectroscopy could be used to distinguish these isomers.
