Topics in Nomenclature Of Organic Compounds And Isomerism
1
IUPAC Nomenclature of Alkanes
- IUPAC (International Union of Pure and Applied Chemistry) provides standardized naming rules for organic compounds
- For straight-chain alkanes: Use word root + 'ane' (methane, ethane, propane, butane, pentane, hexane, heptane, octane, nonane, decane)
- For branched alkanes: Identify longest carbon chain as main chain, number carbons to give branches lowest numbers
2
Nomenclature of Unsaturated Hydrocarbons
- Alkenes contain C=C double bond with general formula CₙH₂ₙ
- Alkenes naming: Word root + position of double bond + 'ene'
- Alkynes contain C≡C triple bond with general formula CₙH₂ₙ₋₂
3
Functional Groups and Their Nomenclature
- Functional groups are atoms/groups that determine chemical properties of organic compounds
- Alcohols (-OH): Replace 'e' of alkane with 'ol' (methanol, ethanol)
- Aldehydes (-CHO): Replace 'e' of alkane with 'al' (methanal, ethanal)
4
Aromatic Compounds
- Benzene (C₆H₆) is the parent aromatic compound with hexagonal ring structure
- Aromatic compounds contain benzene ring with delocalized π electrons
- Benzene derivatives: phenol (C₆H₅-OH), benzoic acid (C₆H₅-COOH)
