Study Notes
Alcohols
- General formula for alcohols is R-OH, where R represents an alkyl group.
- Alcohols classification depends on the number of carbon atoms bonded to the carbon atom holding the hydroxyl group.
Phenols vs. Alcohols
- Phenols have a hydroxyl group (-OH) directly attached to an aromatic hydrocarbon ring.
- This aromatic characteristic provides phenols with higher acidity compared to aliphatic alcohols.
Ethers in Everyday Life
- Ethers are commonly used as solvents in cleaning and extraction processes, such as in the production of perfumes and pharmaceuticals.
Types of Alcohols
- Primary alcohols have the hydroxyl group bonded to a carbon atom that is connected to only one other carbon atom.
- Secondary alcohols have the hydroxyl group on a carbon atom bonded to two other carbon atoms.
- Tertiary alcohols have the hydroxyl group connected to a carbon atom bonded to three other carbon atoms.
Role of Alcohols in Biological Systems
- Alcohols serve as important metabolic intermediates, playing a role in energy production.
- They are involved in the structure of various biomolecules, such as lipids and carbohydrates, influencing biological functions.
