E1 Elimination: Zaitsev Product and Carbocation

E1 elimination often gives the most substituted alkene, called the Zaitsev product. In the example, water acts as a weak base and favors elimination over substitution, so two alkene products can form. The Zaitsev alkene is usually more stable than the Hofmann product because it has more alkyl groups attached to the double bo...

Just like E2 reactions, E1 eliminations are regioselective and form more than one regioisomers.

In this example, water functions as a weak, non-bulky base, and the reaction is heated to favor elimination over substitution, forming two alkenes.

Recall that the stability of alkenes increases with the number of alkyl groups across the...
