This PowerPoint presentation provides an insightful exploration of the properties of hydrocarbons, specifically designed for secondary school chemistry lessons. It delves into how the physical and chemical properties of hydrocarbons change with chain length and their implications for real-world applications. The resource begins with clear learning objectives, such as demonstrating the separation of crude oil into fractions through fractional distillation, describing trends in viscosity, flammability, and boiling point as chain length varies, and linking these properties to the practical uses of hydrocarbons. Starter activities engage students with thought-provoking questions, laying the foundation for the lesson. Core concepts are presented through easy-to-follow explanations and interactive activities. The presentation covers key terms, including boiling point, flammability, viscosity, and volatility, with gap-fill exercises to reinforce understanding. It explains how fractional distillation separates hydrocarbons based on boiling points and explores the properties of smaller versus larger hydrocarbons. For instance, smaller hydrocarbons are more volatile and flammable, making them ideal for cooking gases, while larger hydrocarbons are more viscous and suited for road surfacing.
