Morgan Bailey Mb33295 Stereochemistry Discussion In our 3 rd lab, we experienced the isomerization of dimethyl maleate to dimethyl fumarate. We also analyzed the odors of 2 enantiomers of carvone and noticed that one smells like spearmint and the other smells distinctly different. After this, we examined the optical activity of the 2 different molecules. So it is like we did 3 different experiments all in 1 day. The basic idea of the isomerization of dimethy maleate to dimethyl fumarate was that the C-C double bond would be broken and one side of it would rotate. After that, the double bond would reform and the molecule will have gone from the “Z” conformation to the “E” conformation, making dimethyl fumarate. This experiment demonstrates how a molecule can form a diasteriomer of itself in just a few steps. The basic idea of analyzing the smell of the 2 enantiomers of carvone was that the molecules optical activity, whether it is (+) or (-) will differ. We confirmed this by examining how each one smelt.
