The first part of the experiment dealt with recognizing the difference between two enantiomers. These are molecules that are mirror images of one another, so they have different chemical properties because you cannot take one enantiomer and overlap it over the other. Thus, the enantiomers of these carnove oils have two different smells because they are enantiomers of one another. Different receptors in nose have different binding sites, so one binds and makes one smell while the other makes another. The first enantiomer (+) smelled like dill oil, while the other enantiomer (-) smelled like spearmint gum. We figured out that these were enantiomers using a polarimeter, which is an instrument into which a sample is placed and light is twisted some degrees. Enantiomers have a net twist of zero degrees, so if you measure two compounds which yield a net zero degrees, you are probably dealing with enantiomers. The second experiment deals with diastereomers, which are two molecules that are nonsuperimposable, non mirror images, but have the same molecular formula. They are categorized by E - opposite sides of double bond, or Z – ze same side of the double bond. The experiment dealt with converting dimethyl maleate, which is a Z configuration, into dimethyl fumarate, which is a E configuration of maleate. The mechanism, which is listed under the mechanisms section, explains what happens to force the conversion from maleate to fumarate. The first step was Bromination, which was done via a homolytic cleavage, where one electron goes to each one of the atoms of bromine upon breaking. Heterolytic cleavage is when
