Study Notes
Organic Chemistry
- Organic chemistry is the study of compounds that contain carbon atoms.
- It is based on the properties of carbon atoms, which have a valency of 4 and can form chains, branches, and multiple bonds.
Classes of Organic Compounds
- Alkanes: saturated hydrocarbons with single bonds between carbon atoms.
- Alkenes: unsaturated hydrocarbons with double bonds between carbon atoms.
- Alkynes: unsaturated hydrocarbons with triple bonds between carbon atoms.
- Alkyl halides: halogen-substituted alkanes.
- Alcohols: hydroxyl-functionalized alkanes.
- Ethers: oxygen-functionalized alkanes.
- Aldehydes and ketones: carbonyl-functionalized alkanes.
- Carboxylic acids: carboxyl-functionalized alkanes.
- Esters: carboxyl-functionalized alkanes with an alkyl group.
- Amines: nitrogen-functionalized alkanes.
- Aromatic hydrocarbons: planar, ring-shaped hydrocarbons with delocalized electrons.
Alkanes
- General formula: CnH2n+2
- Examples: methane (CH4), propane (C3H8), butane (C4H10)
