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.

Most substituted alkene is produced as a major product

Explanation:

Dehydration of 3-methyl-2-butanol proceeds through E1 mechanism to form alkenes.Most substituted alkene is produced as major product because of presence of highest number of hyperconjugative hydrogen atoms corresponding to the produced double bond (Saytzeff product).Here, a H-shift also occurs in one of the intermediate step during dehydration to produce more stable tertiary carbocation.Reaction mechanism has been shown below.
