- 1. Tell whether the following pairs of structures are identical or not. 2. For those pairs that are not identical, explain what types of isomers they are. 3. If there are chiral centers, denote them with the correct R,S.chiral. If you were able to make another molecule that is a mirror image of the chiral molecule, the mirror image and the original molecule will be non-superimposable. i.e. the atoms surrounding carbon won't completely align. The lack of alignment of the suround atom makes the two molecules different from each other. The central carbon must be surrounded by 4 different groups. The chiral carbon is highlighted. CH;CH) CHICH2 CH3-C-CH2-CHy OH CH) miror The 3D structure of the above molecule focuses on the chiral carbon and the bond surrounding the chiral carbon. The molecule on the left is different from the molecule on the right (mirror image) because they are non-superimposable. H. CH3-C-COOH HOOC COOH CH NH2 NH2 mimor Answer the following questions: 1.

Draw three structural isomers as possible for CHO.Construct a model in which a tetrahedral carbon atom has four different colored model atoms attached to it- red, green, orange and white representing 4 different atoms attached to the central atom. a) Does the atom have a plane of symmetry? why or why not? b) Now replace the green atom in your model with a second orange atom. Now two of the groups attached to the carbon atom are identical. Does the model now have a plane of symmetry? Describe it. c)A carbon atom has four different groups attached to the stereogenic center.
