Study Notes
Alkanes and Nomenclature
- Alkanes consist of carbon (C) and hydrogen (H) atoms connected solely by single bonds.
- IUPAC naming process involves finding the longest carbon chain, numbering it, naming substituents with the -yl suffix, assigning numbers to each substituent, and completing the name.
Substituents
- Methyl refers to a one-carbon substituent.
- Isopropyl is a three-carbon substituent with a specific branching structure.
Alkenes and Alkynes
- Alkenes are characterized by the presence of carbon-carbon double bonds.
- Alkynes feature carbon-carbon triple bonds.
Numbering in Nomenclature
- The double bond in alkenes receives the lowest possible number during chain numbering.
- Haloalkanes and alcohols also receive the lowest numbering and take precedence over other functional groups.
Alcohols
- Diols indicate alcohols that contain two hydroxyl (-OH) groups.
- Geminal alcohols have hydroxyl groups attached to the same carbon atom.
- Vicinal alcohols possess hydroxyl groups on adjacent carbon atoms.
Other Functional Groups
- Ethers are derivatives of alkanes.
- Formaldehyde and acetaldehyde are examples of aldehydes, which contain a carbonyl group (C=O) with the carbon also bonded to a hydrogen atom.
- Carboxylic acids contain a carboxyl group (-COOH) and are important in organic chemistry.
- Esters are derived from acids, where the hydroxyl group is replaced with an alkoxy group.
- Acyl halides contain a carbonyl group attached to a halogen.
- Amides consist of a carbonyl group attached to a nitrogen atom.
- Nitriles have a carbon atom triple-bonded to a nitrogen atom.
- Ketones have a carbonyl group located within the carbon chain.
- Alcohols pertain to compounds containing one or more hydroxyl (-OH) groups.
- Thiols are similar to alcohols but contain a sulfur atom instead of an oxygen atom.
- Amines are organic compounds derived from ammonia, containing nitrogen atoms.
