12. You've isolated a new molecule and alyva gave a formula of CH... You have ated on the options to the income shown below. (15) Using the NMR spectra collected on the sext page) no circle the correct molecule by: (1) calculating the integration values for the signals in the NMR (write these ce the () sebe integration values akong with the observed plinting to build the pieces that each igral represents (ie. 21.1 CH2CH) - Weile these above the signal in the NMR label the unique carbons ce your choice above by leder - transfer the labels toe sipas in the CNR (1) explain Dekow why be other somers don't fit the spectrum using at least I specife signal from the NMR that doesn't fit the rejected molecule or a specific pral that should have been present but was not 1.0 0.5 PPM 4.0 3.5 3.0 2.5 2.0 23.0 20.9 21.0 Proton NMR integral values -30.3 - 26.8 - 18.7 - 12.9 -8.4 - 173.3 0 20 PPM 160 140 80 120 100 T 180 Carbon 13 NMR
