This Hydrocarbons course is strictly aligned with the Nigerian Chemistry curriculum for Form 4 O-Level students. It provides a structured approach to organic chemistry, focusing on the classification, properties, and reactions of Alkanes, Alkenes, and Alkynes. Learners will achieve the following practical outcomes: 1. Apply IUPAC nomenclature rules to name and draw structural formulas for organic compounds. 2. Distinguish between saturated and unsaturated hydrocarbons using standard chemical tests. 3. Describe the laboratory preparation, physical properties, and chemical reactions of methane, ethene, and ethyne. 4. Analyze the fractional distillation of petroleum and the industrial significance of cracking and reforming. 5. Solve exam-standard questions regarding structural isomerism and molecular formula determination. This course emphasizes assessment readiness, ensuring students are equipped for O-Level examination requirements. Key strengthening areas include reaction mechanisms, identifying functional groups, and understanding the environmental impact of hydrocarbon combustion.
