1. You are given a mixture of compounds that differ from one another only in their three-dimensional shape and configuration. What type of isomers must these compounds be?

2. Depending on the configuration of the double bond, each of the reactions below gives a different six-membered-ring product. How would you describe the selectivities of the reactions?

About This Quiz & Worksheet

Regioselectivity, chemoselectivity and stereoisomers are reactions and compounds in organic chemistry. Test your knowledge of these concepts by answering multiple-choice questions on key subjects such as a reaction that produces a major and minor product and a mixture of compounds that are different from each other only in their three-dimensional shape and configuration.

Quiz & Worksheet Goals

See how much you know about these topics:

  • The selectivities of reactions that give a different six-membered-ring product
  • Term for two compounds that have the same chemical formula but different atom connectivities
  • An example of a certain kind of reaction

Skills Practiced

  • Reading comprehension - make sure you understand the most important information about the selectivities of chemical reactions that each give a six-membered-ring product
