Petroleum & homologous series
Narrated lesson · press play
Crude oil is a treasure chest of hydrocarbons — fuels, plastics and more. Learn how fractional distillation separates petroleum into useful fractions, what a homologous series is, and how isomers give the same formula different structures.
What you'll learn in this lesson
By the end you should be able to (NSSCO Chemistry 10.2):
- Name the fuels coal, natural gas and petroleum; name methane as the main constituent of natural gas
- Describe petroleum as a mixture of hydrocarbons separated into fractions by fractional distillation
- Name the uses of the fractions (refinery gas, gasoline, naphtha, kerosene, diesel, fuel oil, lubricating, bitumen)
- Describe a homologous series and recall that members share a general formula
- Identify and describe structural isomerism (C₄H₁₀, C₅H₁₂, C₃H₇OH)
