Chapter 22, Problem 1E
Interpretation Introduction

Interpretation:

The Lewis diagram of the general structure of an amino acid is to be drawn.

Concept introduction:

The Lewis diagram shows the bonding between different atoms of a molecule and the lone pairs of electrons in the molecule. It shows how the valence electrons of an atom are arranged in the molecule. In Lewis diagram, two electrons between the atoms are indicated as a line to show bonding between atoms.

Explanation of Solution

The Lewis structure of a compound shows how the valence electrons of an atom are arranged in the molecule. The molecular structures are given by its valence electrons and lone pairs on central atom.

The total number of valence electrons in an amino acid is the sum of valence electrons of two carbon atoms, valence electrons of four hydrogen atoms, valence electrons of one nitrogen atom and valence electron of two oxygen atoms. There are four valence electrons on carbon atom, one valence electron on each hydrogen atom, five valence electrons on nitrogen atom and six valence electrons on each oxygen atom. Therefore, the total number of valence electron in an amino acid is 29. The Lewis diagram of an amino acid molecule is shown below in Figure 1.

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
