Alcohols, Phenols And Ethers — Syllabus & Topics

Topics covered in Alcohols, Phenols And Ethers for AP EAPCET Chemistry.

Topics in Alcohols, Phenols And Ethers

1

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)
2

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
3

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)
4

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)
