Revision Notes — Alcohols, Phenols And Ethers
Key concepts, formulas, and definitions from Alcohols, Phenols And Ethers for CUET (UG) Chemistry preparation.
Key Topics to Revise
Classification and Nomenclature
- Alcohols are classified as primary (1°), secondary (2°), or tertiary (3°) based on carbon bearing -OH group
- Monohydric alcohols: C₍ₙ₎H₍₂ₙ₊₁₎OH; Polyhydric alcohols: contain multiple -OH groups
- Phenols contain -OH group directly attached to aromatic ring (C₆H₅OH)
Preparation Methods
- Alcohols from alkenes: Hydration (Markovnikov) and Hydroboration-oxidation (Anti-Markovnikov)
- From carbonyl compounds: Reduction of aldehydes → 1° alcohols, ketones → 2° alcohols
- Grignard synthesis: RCHO + R'MgX → 2° alcohol; R₂CO + R'MgX → 3° alcohol
Physical Properties
- Alcohols: Higher boiling points than hydrocarbons due to hydrogen bonding
- Solubility decreases with increasing carbon chain length
- Boiling point order: 1° > 2° > 3° (for same carbon number)
Chemical Properties - Alcohols
- Acidity order: 1° > 2° > 3° (due to +I effect of alkyl groups)
- Reaction with Na: 2R-OH + 2Na → 2R-ONa + H₂
- Dehydration: Ease order 3° > 2° > 1° (follows Saytzeff rule)
