Stereochemistry and Isomerism

Stereochemistry deals with the three-dimensional structure and properties of molecules. It explains the arrangement of atoms and their manipulation within a molecule in a 3D structure. Stereochemistry can be dealt with all types of molecules. Based on the stereochemistry of a molecule, the physical and chemical properties of the molecules vary.

Question

5. Construct models of all the stereoisomers of 1-bromopropene. Draw the line structure of your
models. Are these molecules isomers? If they are isomers to what specific category do they
belong? Assign E or Z descriptors to each compound, if appropriate.
6. Construct a model of dibromochloromethane and draw the perspective structure. How many
planes of symmetry does this molecule possess? Construct the mirror image of your model. Are
the two models superimposable? Classify or describe the relationship between these two mirror
images, and assign R or S descriptors, if appropriate.

Using your model, construct an energy diagram to show the variation in the free energy of the molecule as the FRONT ATOM is rotated CLOCKWISE from 0º to 360º in 60º increments. In your energy diagram, you should clearly show the relative energies of each conformer.
Build a model of 2,2,5,5-tetramethylhexane. Orient the model so that you are looking at the carbon with the arrow pointing to it in Figure 3. Align the bond to the next carbon in the chain so that it is directly behind the first carbon to match a Newman projection view. (See Figure MM.3 in the lab manual) Spin the carbons on either side of the bond you're looking down to cycle through all three staggered and all three eclipsed positions of the substituents. Draw all six positions as Newman projections on the data sheet and identify the position with the highest energy. Draw the six Newman projections of all of the different energy levels. Label each as staggered or eclipsed and rank in order from lowest energy to highest.
