1-Make two identical models of methane with four different colored balls attached to each carbon. on one model switches two of the balls. drwa the two structure in steroscopic projection with dashes, wedges and label each hydrogen.
2- Are these structures identical or are they different? if they are different how are they different? what is the relationship between the two structures?
Homework Answers
Hence, we see that structure B is actually exactly similar to the mirror image of structure A. Hence, as we have marked the hydrogens, the two structures are non-identical non-superimposable mirror images which are called enantiomers. Hence, they differ only by the spatial arrangement of atoms in space, but have the same bonds.
Note that if the hydrogens are not numbered or color coded, we can not distinguish between the hydrogens and the structures will be indistinguishable. That is why a carbon stereocenter has four different groups attached.

3. Diastereomers and Meso Forms. When a molecule has two or more stereogenic centers, stereoisomers that are not mirror images can exist; these are called diastereoisomers. Within this general class, there are special types of stereoisomers that are always optically inactive and are called meso forms. Construct a model with four different colored balls about a carbon center. Construct another identical to the first and verify this by the superimposition test. Now remove the same colored balls, blue (C from...
