Question

Acid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an E1 mechanism. The first step is the protonation of alcohol and oxygen to form an oxonium ion.

Dehydration of 3-methyl-2-butanol forms one major and two minor organic products. Draw the structures, including hydrogen atoms, of the three organic products of this reaction.

The 3.) is correct that is the minor product I came up with but I cant get the answer correct for 1.) major product? and 2.) minor product

Answer 1

Look at the picture.

Step-by-step explanation:

The reaction will go to the most substituted alkene because thermodynamically they are the most stable.
