Topic 1: Crude Oil And Hydrocarbons Flashcards
What is CH4?
-Methane.
What is Fractional Distillation?
- Different fractions have different chain lengths.
- larger fractions have stronger forces of attraction between molecules.
- Stronger forces of attraction more energy is needed to overcome.
- The fractional column has a temperature gradient.
- So different fractions condense off at different places.
What is C2H6?
-Ethane.
What are the products of fractional distillation?
- Riffinary gasses.
- Gasoline.
- Kerosene.
- Desil.
- Lubricating oil, fuel oil, bitumen.
- Fuel oil.
- Bitumen.
- Rushbrooks girls keenly devour lettuce for breakfast.
What is C3H8?
-Propane.
Define The Alkanes?
-A homologous series of hydrocarbons, who’s formula go CnH2n+2.
What is a Homologous Series?
-A family of compounds that have a similar chemical properties, a trend in physical properties and the same general formula.
What is C4H10?
-Butane.
Order of atoms starting from one carbon?
- Methane.
- Ethane.
- Propane.
- Butane.
- Pentane.
- Hexane.
- Octane.
- Monkeys eat peeled bananas politely.
Define isomers?
-Molecules that have the same molecular formula but different display formula are called isomers. Isomers have different chemical and physical properties to each other.
Define complete combustion?
-When there is enough oxygen for a hydrocarbon to fully com-bust.
What does 2,methlybutane look like?
-Has 4 carbons in the main line and one branch coming off second from the end.
What does 2,2 diemethlyheptane look like?
-5 carbons in main line, 2 branches second from the end.
What does 3 ethyl heptane look like?
-5 carbons in main line, and a branch with 2 carbons coming off 3 atoms across.
Define the Alkenes?
-These are unsaturated and they have a double bond.
What does Alkene C2H4 look like?
-To carbons joint by double bond, remember atoms can have a max of 4 forces of attraction. Ethene.
How is crude oil formed?
-Crude oil is formed over thousands of millions of years. It is mostly dead fish and animals as re-compacted in Sea. People drill crude oil oil rigs. It is then extracted and distilled in a fractional distillation column.
What are The Alkahols?
-These are not hydrocarbons, has a -OH and a different suffix.
Methane?
-CH4
Ethane?
-C2H6
Propane?
-C3H8
2-methylpropane?
-C4H10
Butane?
-C4H10
Octane?
-C8H18
2-methylbutane?
-C5H12
Pentane?
-C5H12
2-methylpentane?
-C6H14
Hexane?
-C6H14
