Chapter 10, Problem 10.64P
Interpretation Introduction

Interpretation:

The complete mechanism that leads to the three alkenes produced by N-ethylhexan-3-amine under Hofmann elimination conditions is to be drawn, and the major product is to be predicted.

Concept introduction:

Hofmann elimination is an E2 elimination of an amine group along with a β hydrogen to produce an alkene. Unlike most elimination reactions that preferentially form the most substituted alkenes, Hofmann elimination preferentially forms the least substituted alkene.

When two different types of β hydrogens are present, the one from the less substituted carbon is removed preferentially. The leaving group in Hofmann elimination is a bulky tertiary amine group NR3. An E2 reaction is a single-step concerted reaction. It requires that the two groups that are eliminated must be anti to each other. The most stable conformer has the β hydrogen in anti position on the less substituted carbon. This gives a least substituted alkene as the major product.

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
