Chapter 11: Organic Chemistry
Organic Chemistry is the study of carbon-containing compounds and their properties, structures, and reactions. This chapter introduces students to the fascinating world of organic molecules, which form the basis of life and many synthetic materials. Students will learn about the classification, nomenclature, and various reactions of organic compounds, laying the groundwork for more advanced topics in organic chemistry.
Key Topics Covered:
- Introduction to Organic Chemistry
- Definition and scope of organic chemistry.
- Importance of organic compounds in everyday life.
- Bonding in Carbon Compounds
- Unique properties of carbon: tetravalency and catenation.
- Hybridization: sp³, sp², and sp hybridization.
- Classification of Organic Compounds
- Hydrocarbons: alkanes, alkenes, and alkynes.
- Functional groups: alcohols, aldehydes, ketones, carboxylic acids, amines, and others.
- Homologous series and their significance.
- Nomenclature of Organic Compounds
- IUPAC system of nomenclature.
- Naming alkanes, alkenes, alkynes, and compounds with functional groups.
- Common names vs. systematic names.
- Isomerism
- Structural isomerism: chain, position, and functional group isomerism.
- Stereoisomerism: geometrical (cis-trans) isomerism.
- Hydrocarbons
- Alkanes: structure, properties, and reactions (combustion, substitution).
- Alkenes: structure, properties, and reactions (addition reactions, polymerization).
- Alkynes: structure, properties, and reactions.
