Worksheet 11: Types of Stereoisomers, Identifying Number of Stereoisomers Leader: Hannah J. Course: Chem 331 Instructor: Dr. Winter Supplemental Instruction Date: 9/24/15 Iowa State University 1) Choose the statement(s) that describe each of the following terms: a. Stereoisomers that are non-superimposable mirror images of each other b. A 50:50 mix of enantiomers c. Stereoisomers that are not mirror images of each other d. Molecules that have the same molecular formula and sequence of bonded atoms, but differ in their 3-D arrangement of atoms in space e. A molecule with chiral centers that is achiral overall due to a plane of symmetry. f. Stereoisomers that differ in only one physical property, the rotation of planepolarized light g. Stereoisomers that have completely separate physical properties Stereoisomers: Enantiomers: Diasteromers: Racemic Mixture: Meso Compound: 2) Draw a pair of molecules for each of the following that are examples of each term. Your examples do not have to be different for each term, but if they are the same, please explain how/why they fit the categories you have chosen: a. Stereoisomers: b. Enantiomers: 1060 Hixson-Lied Student Success Center 515-294-6624 email@example.com http://www.si.iastate.edu c. Diasteromers: d. Racemic mixture: e. Meso Compound: 3) For the following molecule, calculate the maximum possible stereoisomers and then identify how many different stereoisomers it will actually have. Explain why your answers are or are not different.
