Hydrocarbons Flashcards
what kind of bonds are in alkanes?
C-C
General formula of alkanes?
CnH2n+2
What does the term homologous series mean?
A group of organic compounds that react in a similar way
How man bonds are on each carbon atom in an alkane?
4
What makes something saturated?
No spare bonds in the structure
What are the first four alkanes?
Methane
Ethane
Propane
Butane
What happens to the viscosity of hydrocarbons as the length increases?
It becomes less runny (more viscous)
How does the boiling point change when hydrocarbons get longer or shorter?
Longer = higher boiling point Shorter = lower boiling point
What is the fancy way of saying how easily something will boil?
Volatile
Which hydrocarbons are more likely to catch fire, short or long ones?
Shorter ones
What is complete combustion?
The complete breakdown of a hydrocarbon
What is required for complete combustion?
Oxygen
What are the waste products of combustion?
Carbon dioxide + water
What is the question for complete combustion?
Hydrocarbon + oxygen > CO2 + H2O
What process happens to the carbon and hydrogen atoms during combustion?
They are oxidised
