Acid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an El mechanism. The first step is the protonation of the alcohol 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.

Question

Answer is two minor and one major product 

**Title: Acid-Catalyzed Dehydration of Alcohols** **Introduction:** The acid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an E1 mechanism. The first step is the protonation of the alcohol oxygen to form an oxonium ion. **Dehydration Reaction:** **Reactant:** 3-methyl-2-butanol **Reaction Process:** - The alcohol oxygen is protonated, resulting in the formation of an oxonium ion. - The oxonium ion undergoes dehydration, leading to the formation of an alkene. **Products:** - **Major Product:** The most stable alkene formed. - **Minor Products:** Two other possible alkenes that are less stable. **Diagram Explanation:** - The reaction pathway is shown starting with 3-methyl-2-butanol. - After protonation, an oxonium ion intermediate is formed. - This intermediate then forms a major product and two minor products. **Interactive Section:** - Two boxes labeled "Draw the major product" and "Draw minor product 1". - Tools provided for drawing include selection, drawing lines, erasing, and adding carbon/hydrogen atoms. - The interface provides options to select rings and additional drawing elements. **Conclusion:** Understanding the acid-catalyzed dehydration process helps in predicting the major and minor products of alcohol reactions, which is essential in organic synthesis and reaction mechanism studies.
