5.7.1.1 crude oil, hydrocarbons and alkanes Flashcards
What is a crude oil
A finite resource found in rocks
Crude oil is the remains of..
ancient biomass, mainly plankton
What is crude oil a mixture of?
very large compounds, mostly hydrocarbons- molecules made up of hydrogen and carbon only.
What are alkanes?
any of the series of saturated hydrocarbons including methane, ethane, propane, butane and higher members.
Define saturated
containing the greatest possible number of hydrogen atoms, without carbon–carbon double or triple bonds.
Define unsaturated
having carbon–carbon double or triple bonds and therefore not containing the greatest possible number of hydrogen atoms.
What is the general formula for the homologous series of alkanes
CnH2n+2
List the first four members of alkanes
Methane, ethane, propane and butane
What are the two ways in which alkanes can be represented
CnH2n+2 or bond model
Define homologous
Carbon/hydrogen molecules which have the same relation to each other
Define heterogenous
Carbon/hydrogen atoms which have an unalike relation to each other
