Student Learning Objective: Predict the products of dehydrohalogenation and use Zaitsev's rule to predict the major and minor products 7.11: Positional Orientation of Elimination: Zaitsev's Rule Problem-Solving Hint: 1. Zaitsev is transliterated from the Russian name, and may also be spelled Saytzeff Whenever a carbocation has the positive charge on a carbon atom next to a more highiy substituted carbon, consider whether a rearrangement might occur. 2. When...
