- Crude Oil
- A dark liquid which we can extract from the ground.
- Contains many different chemical compounds
- Almost all of these compounds are hydrocarbons
- Hydrocarb-ons are compounds containing only hydrogen and carbon
- Most of the hydrocarbons found in crude oil are alkanes
- The general formula for alkanes is CnH2n+2
- Almost all of these compounds are hydrocarbons
- Contains too many fractions to be useful straight from the ground
- Fractions are substances with similar boiling points
- During fractional distillation, hydrocarbons with similar numbers of carbon atoms are separated into fractions
- Hydrocarbons
- The properties of hydrocarbons vary with their chain legnth.
- Hydrocarbons with many carbon atoms have a longer chain legnth
- Shorter chains are more volatile
- Volatility is the tendency to turn into a gas
- Longer chains are more viscous
- Viscosity is how thick and sticky a fluid is
- Shorter chains are more flammable
- Longer chains have a higher boiling point
- The properties of hydrocarbons vary with their chain legnth.
- Fractional Distallition
- During fractional distillation, hydrocarbons with similar numbers of carbon atoms are separated into fractions
