Question
**Propose Mechanisms for the Following Reactions** Consider \( \text{H}_2\text{SO}_4 \) as the acid catalyst in these reactions. a) Reaction 1: - Starting compound: A five-carbon chain with a hydroxyl group (OH) and a deuterium (D) atom. - In the presence of \( \text{H}^+ \) and heat, the products are two different alkenes: - Alkene 1: Five-carbon chain with double bonds at positions 2 and 3, with D and H positioned on the carbons involved in the double bond. - Alkene 2: Similar structure to Alkene 1 but with a different position for D and H. b) Reaction 2: - Starting compound: A four-carbon chain with a hydroxyl group (OH) attached to the second carbon. - In the presence of \( \text{H}^+ \) and heat, the products are: - Alkene 1: A branched alkene with a double bond between a terminal carbon and its neighbor. - Alkene 2: An alkene with a similar structure but involving a different terminal carbon and its neighbor. c) Reaction 3: - Starting compound: A six-carbon chain with two hydroxyl groups (OH) at positions 2 and 3. - In the presence of \( \text{H}^+ \) and heat, the products include a ketone: - A six-carbon chain with a carbonyl group (C=O) at the second carbon. These reactions illustrate acid-catalyzed dehydration and rearrangement processes.
