Summary
Organic chemistry involves the study of carbon-containing compounds, focusing on their structure, properties, and reactions. It includes understanding hazards, homologous series, functional groups, and types of reactions.
- Hazard — anything that could cause harm. Example: Flammable substances can ignite easily.
- Homologous Series — a group of compounds with similar properties and the same functional group. Example: Alkanes like methane and ethane.
- Functional Group — specific atoms that determine a compound's properties. Example: Alcohols have a hydroxyl (-OH) group.
- Nomenclature — systematic naming of organic compounds. Example: Methanol is named for its single carbon and hydroxyl group.
- Homolytic Fission — bond breaking where each atom retains one electron. Example: Cl2 splitting into two Cl radicals.
- Heterolytic Fission — bond breaking where one atom retains both electrons. Example: HCl splitting into H+ and Cl- ions.
- Electrophile — an electron-poor species that accepts electrons. Example: Carbocations.

Common Confusions
- Difference between homolytic and heterolytic fission
- Distinguishing between electrophiles and nucleophiles
Typical Exam Questions
- What is a homologous series? A group of compounds with similar properties and the same functional group.
- How does homolytic fission differ from heterolytic fission? Homolytic fission results in radicals, while heterolytic fission results in ions.
- What is an electrophile? An electron-poor species that accepts electrons.
What Examiners Usually Test
- Understanding of functional groups and their properties
- Ability to name organic compounds using IUPAC nomenclature
- Mechanisms of organic reactions, such as radical chain reactions
