Interpretation Introduction
Interpretation:The cis/trans ratio refers to in permethrin needs to be predicted.
Concept Introduction:Permethrin is a synthetic insecticide containing ester group. They are used in commercial clothing and agricultural products. In cis-isomer, the atom or groups linked to the ring are on the same side of the ring or double bond. In trans-isomer, the atom or groups linked to a ring are on the opposite sides of the ring or double bond.

1. Calculate the accurate monoisotopic mass (using all 1H, 12C, 14N, 160 and 35CI) for your product using the table in
your lab manual. Don't include the Cl, since you should only have [M+H]*. Compare this to the value you see on
the LC-MS printout. How much different are they?
2. There are four isotopic peaks for the [M+H]* ion at m/z 240, 241, 242 and 243. For one point of extra credit,
explain what each of these is and why they are present.
3. There is a fragment ion at m/z 184. For one point of extra credit, identify this fragment and confirm by
calculating the accurate monoisotopic mass.
4. The UV spectrum is also at the bottom of your printout. For one point of extra credit, look up the UV spectrum
of bupropion on Google Images and compare to your spectrum. Do they match? Cite your source.
5. For most of you, there will be a second chromatographic peak whose m/z is 74 (to a round number). For one
point of extra credit, see if you can identify this molecule as well and confirm by…
Please draw, not just describe!
can you draw each step on a piece of a paper please this is very confusing to me
