Final answer:
The conversions include hydrogenation for alkene to alkane, dehydration for alcohol to alkene, acid-catalyzed hydration for alkyne to alcohol, and strong oxidation for alkane to alcohol.
Step-by-step explanation:
The question asks about the series of reagents that could be used for specific chemical conversions between different classes of organic compounds. Here are the series of reagents for each conversion:
- A) Alkene to alkane: Addition of hydrogen (H₂) in the presence of a metal catalyst such as palladium or platinum, which is known as hydrogenation.
- B) Alcohol to alkene: Dehydration of alcohol in the presence of an acid catalyst, typically sulfuric acid (H₂SO₄), to form an alkene and water.
- C) Alkyne to alcohol: Hydration of an alkyne in the presence of a strong acid and water, leading to the formation of an enol which immediately tautomerizes to a ketone or aldehyde;
- D) Alkane to alcohol: Oxidation of an alkane which typically requires a strong oxidizing agent, such as potassium permanganate (KMnO₄) or chromic acid (H₂CrO₄), to introduce the hydroxyl (-OH) group.
