Edexcel IGCSE Chemistry: Crude Oil and Alkanes PPT

This PowerPoint Presentation covers most of the requirements for the Crude Oil and Alkanes units for Edexcel IGCSE Chemistry in a clear and coherent manner.

These slides may also be useful for other exam boards, such as AQA, WJEC, CIE, etc., if modified after download.

Specification statements covered include:

• know that crude oil is a mixture of hydrocarbons
• describe how the industrial process of fractional distillation separates crude oil
  into fractions
• know the names and uses of the main fractions obtained from crude oil: refinery gases, gasoline, kerosene, diesel, fuel oil and bitumen
• know the trend in colour, boiling point and viscosity of the main fractions
• know that a fuel is a substance that, when burned, releases heat energy
• know the possible products of complete and incomplete combustion of hydrocarbons with oxygen in the air
• know the general formula for alkanes
• explain why alkanes are classified as saturated hydrocarbons
• understand how to draw the structural and displayed formulae for alkanes with up to five carbon atoms in the molecule, and to name the unbranched-chain isomers
• describe the reactions of alkanes with halogens in the presence of ultraviolet
  radiation, limited to mono-substitution
