Pre-lecture Reading Assignment: Stereoisomers

Quick Intro

Previously we learned that molecules that have the same molecular formula but have atoms that are connected in a different order are called isomers. In this chapter we will learn about a special type of isomers that have all the same atoms bonded to each other but only differ by how atoms are arranged in space. These are called stereoisomers and are especially important for biological and medical applications!

 

Objectives

• Distinguish between constitutional isomers and stereoisomers.
• Identify stereocenters in a molecule.
• Determine whether a molecule is chiral (except molecules with multiple stereocenters...we'll get to those a little later).
• Recognize pairs of enantiomers.
• Draw the enantiomer of a chiral molecule.
