10. You are working in the lab, getting ready to perform a Grignard reaction on propiophenone (structure shown below). However, when you look for the bottle of this reagent, you find two bottles whose labels have fallen off. You find the labels and see that one says "propiophenone", while the other says "benzyl methyl ketone" (structure shown below), but you don't know which label came from which bottle. 8 propiophenone benzyl methyl ketone You need to perform the reaction on the right starting material, but the only analysis technique you have available to you is a mass spectrometer. You quickly collect the mass spectra for the two compounds in the bottles, and obtain the following results. Bottle 1: 100 80 60F 20 Bottle 2: 43 91 M+- 134 Mass Spectrum C9H100 40 80 120 160 200 240 280 m/e 100 105 77 80 60 M+ 134 Mass Spectrum C9H100 40 80 120 160 200 240 280 m/e Which bottle contains your desired propiophenone? Explain your rationale. (10 pts)

The nitro groups on the benzene ring in the reactant serve two purposes.One is to let you know what atoms in the reactant correspond to what atomsin the product. But what role do the nitro groups play electronically – whywould the reaction be much slower if these nitro groups weren’t attached tothose benzene carbons? Draw any relevant structures to support youranswer.
