Questions & Answers

Q: How do alcohols play a protective role in hand sanitizers?

Alcohols in hand sanitizers denature proteins, destroying the outer shells of viruses and bacteria, effectively killing them and preventing infections.

Q: What are some ways to synthesize alcohols?

Alcohols can be synthesized through acid-catalyzed hydration of alkenes, substitution reactions with haloalkanes, or by reacting alkenes with osmium tetroxide to produce diols.

Q: How can alcohols be converted into alkyl halides?

Alcohols can be converted into alkyl halides using reagents like hydrogen halides, phosphorus tribromide, or thionyl chloride, which replace the hydroxyl group with a halide, making it a better leaving group.

Q: What are epoxides and how can they be formed?

Epoxides are cyclic ethers formed by the reaction of alkenes or halohydrins. They are highly reactive compounds and can be opened either by acid-catalyzed or base-catalyzed reactions.

Summary & Key Takeaways

• Alcohols, such as ethanol, can be found in alcoholic drinks but can also be toxic in larger quantities.

• Alcohols like ethanol, propanol, or isopropanol are commonly found in hand sanitizers, where they denature proteins, killing viruses and bacteria.

• Alcohols can be used as building blocks to synthesize other oxygen-containing organic compounds like ethers and epoxides.
