About This Quiz & Worksheet

Find out what you know about diastereomers with this multiple-choice quiz. Questions will cover topics like the classification of two otherwise-similar chemical compounds that occupy three-dimensional space differently and the number of different substituents a carbon atom needs to be bonded to in order for it to be classified as a stereocenter.

Quiz & Worksheet Goals

Quiz your knowledge of the following areas:

  • Determining the stereochemical relationship between given compounds
  • Two compounds with exactly opposite stereochemical configurations relative to one another
  • Whether or not compounds are diastereomers of each other

Skills Practiced

  • Information recall - access the knowledge you've gained regarding the term for two chemical compounds with the same chemical formula and atom connectivity but different ways of occupying three-dimensional space
  • Making connections - use your understanding of chemical compounds and how they're connected to each other via a stereochemical relationship
  • Knowledge application - use your knowledge to answer a question about the number of different substituents a carbon atom must be bonded to in order for it to be considered a stereocenter
