If you have a reaction with a strong but huge, bulky base like (CH3)3CO-, then it will most likely yield a Hoffman product with a less substituted double bond because the base will have a hard time reaching and attacking the most substituted carbon atom. Smirnova, Guoquan Zhang, Hark Hoe Tan, Chennupati Jagadish, Yuri S. The ratio of Zaitsev/Hofmann (Z/H) products in the hydroxide elimination of 2-bromo-2-methylbutane is not necessarily the same as the Z/H ratio in the acid-catalyzed equilibration of the two isomers.

The Oscar winning best actors have a mean age of 43. The ratio of Zaitsev/Hofmann (Z/H) products in the hydroxide elimination of 2-bromo-2-methylbutane is not necessarily the same as the Z/H ratio in the acid-catalyzed equilibration of the two isomers. Zaitsev's rule simply states that when you have the option to form more than one form of a double bond, you should choose the double bond that is most stable. follow Zaitsev rule ( Saytzeff, Saytseff, or Saytzev ).
