Study Notes
- Organic chemistry is a branch of chemistry studying carbon-containing compounds.
- Organic compounds show variety and include simple molecules like methane (CH4), as well as complex molecules like proteins, carbohydrates, and DNA.
- Organic chemistry's significance stems from the presence of organic compounds in medicine like pharmaceuticals and antibiotics, food like sugars and oils, plastics like polyethylene, fuels like natural gas and petrol, and biochemistry like in enzymes and hormones.
Carbon's Special Properties
- Carbon is a crucial element in organic chemistry.
- Carbon has 4 valence electrons enabling it to form 4 covalent bonds.
- Note that these are covalent bonds and not ionic.
- Carbon atoms can bond and form long chains, rings, or branched structures, making complex structures.
- The element can form single, double, and triple bonds.
- Carbon's versatility allows for a vast array of molecular structures and isomers (molecules with the same molecular formula but different structures).
- More bonds equal more strength.
Types of Organic Compounds
- Organic compounds are classified into different types based on their structure and bonding.
- Important types of organic compounds include cycloalkenes and arenes.
- "ane" indicates a single bond
- "ene" indicates a double bond
- "yne" indicates a triple bond
Alkanes (Saturated Hydrocarbons)
- Alkanes feature single bonds between carbon atoms.
- The general formula for alkanes is CnH2n+2
- Examples of alkanes include Methane (CH4), Ethane (C2H6), and Propane (C3H8).
Hydrocarbons
- Consist of only hydrogen and carbon atoms.
