E2 Mechanism: Complete Guide (Compilation Video)

Описание: Everything you need to know about E2, bimolecular elimination: mechanism, Zaitsev's Rule for determining major products, when Zaitsev's Rule FAILS, and tricky cases like cyclic structures and choosing the major product between a pair of cis/trans isomers. (Zaitsev's Rule is also called Zaytsev's Rule, Saytzeff's Rule, or Saytzev's Rule.)
