Unknown compound Z gives the following spectroscopic data. It was made using a
reaction in these chapters. The MS gives a parent ion at m/z = 112.09 that is also the
base peak and an M+1 peak at m/z = 113.09 that is 7.6% as intense, meaning that
compound Z has 7 carbons in total. Elemental analysis shows that the compound only
contains C, H, and O. The UV shows a Amax = 210 nm. The IR shows important peaks at
2860-2960 cm 1, 2748 and 2648 cm¹, 1715 cm ¹, and 1640-1680 cm ¹. The ¹H NMR
shows peaks at 10.21 (s, 1H), 2.37 (q, 2H, J-7.7 Hz), 2.14 (s, 3H), 1.71 (s, 3H), and 1.06 (t,
3H, J-7.7 Hz) ppm 6. The 13C NMR shows peaks at 191.0, 162.0, 130.1, 26.0, 18.6,
11.9, and 10.4 ppm 8. DEPT-135 shows peaks at 191.0, 26.0 (negative signal), 18.6,
11.9, and 10.4 ppm 8. What is the IUPAC name of the compound? (Note: don't worry
