Transcribed Image Text:10.3 THE STEREOCHEMICAL OUTCOME OF AN E2 REACTION
The examples in the previous section focused on regiochemistry. We will now focus our attention on stereochemistry. For example, consider
performing an E2 reaction with the following substrate:

This substrate has two identical ß positions so regiochemistry is not an issue in this case. Deprotonation of either ß position produces the
same result. But in this case, stereochemistry is relevant, because two stereoisomeric alkenes are possible:
