Question

on the GC-MS Spectrum i have to do this.

here is the reaction

On the GC-MS spectra, what is the key piece of information that illustrates that you most likely made your desired product? Be specific. Answer in one sentence. 9. 10. One of the most frequently made fragments has a m/z 121. In box 1, draw a picture of this fragment. In box stable. Two hints to help you with Box 2: 1) Every atom in Box 2 MUST obey the octet rule if you have the correct response; 2) You never want to break aromaticity 2, draw a resonance structure of this fragment that illustrates why it is so Box 1 Box 2 11. If, after you made the Grignard reagent, water somehow got into your reaction flask, what would have happened? Show me what product(s) would have been made by pushing all arrows showing all reaction intermediates, and showing all formal charges. 1.8e+07 16e+07 1.40+07 1.2e 07 e+07 8000000 6000000 4000000 2000000 3.90 Tme 210 220 2.30 240 2.50 2.60 270 280 20 300 310 3.20 3.30 3.40 350 360 370 380 Scan 31 (2.274 min): Samia.D'data.ms Abundance 6000000 5500000 5000000 4500000 3500000 3000000 2500000 2000000 1500000 1000000 500000 43.1 77.1 57.1 91.1 105.0 132.1 29.1 65.1 141.1 150.1 mizo 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 200 210 (i) Draw a picture of the product with an arrow pointing to the peak on the GC trace that represents that product. (i) On the top of the GC trace, write down the information that would be necessary for someone to reproduce your GC-MS results. Mg diethyl ether 2.
