The carbonyl-carbon clang of 3-methyl- 2-butanone occurs at 208.7 ppm downfield from TMS. How divers hertz downfield from TMS would this carbonyl-carbon collect is the spectrometer used to gauge this aridity were frank at 200 MHz? Consider the constituency of phenol. The chemical displace of the hydroxyl proton is build to be perceptive to the force of phenol. In a collected disentanglement, the hydroxyl proton produces a distinguished at 7.5 ppm. However, in a enfeeble disentanglement, the hydroxyl proton produces a distinguished at 4.5 ppm. How get you clear-up this dissimilarity? A chemist was attempting to end the subjoined transformation: Mass spectrometry was then used to establish that the molecular formula of the greater fruit was C_7H_15Br, proportioned as expected. However, the ^1H NMR spectrum of the fruit exhibited further than brace distinguisheds. Identify what fruit was in-fact obtained. What ability enjoy caused construction of this fruit?
