How would you interpret this IR spectra of fluorene? What I mean by this is which peaks let you know its fluorene and which peaks show impurities if any such as 9-fluorenone since this lab required a separation of fluorene and 9-fluorenone. Other impurities could be solid alumina and sand and the solvents of pet. ether and dichlormethane.

References] The molecular ion in the mass spectrum of 3-methyl-2-pentene appears at m/z 84. Propose a structural formula for the prominent peak at m/z 29. • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • In cases where there is more than one answer, just draw one. • Do not use the square brackets tool in your answer.

Match the molecules from the drawings that is most likely to have produced each of the three Mass Spectrum. Then identify the likely breakdowns that yield each major peak.

5. The proxluct of the reaction below gives the IR spectrum shown. Although you are unfamiliar with the rcaction, usc your knowledge of IR spectroscopy to predict a likely product. (Note: the number of carbon atoms in the product is the same as in the starting material.) Page 4 OH Al(OiPr)3 acetone no 4000 c hle belveen sall rlate cas. e Ged LIFE

For each structure, list the bond stretches that will produce separate bands in the IR between 4000 and 2000 cm-1 and give approximate frequency.

Say you’ve just ran your unknown sample on the uv/vis and realized theabsorption is greater than the largest absorption of your standard curve. This is bad from a quantitative standpoint, as we can’t compare our standard curve with our data. What would you need to do to fix the problem? (Hint: there are two possible answers for this.)

Analyze the following GCMS spectra. In your analysis of each GC-MS spectrum, include: a) The structure of the compound b) The molecular ion (M*) and its corresponding m/z value (if shown in the spectrum) c) The base peak and its corresponding m/z value d) Provide the fragmentation pattern of the molecule. Be sure to clearly indicate the cations and/or radical fragments and their corresponding m/z value from the spectrum.
