Organic chem

• Hydrocarbons

  -compounds that are made up of hydrogen and carbon atoms only
• Crude oil (mainly made up of hydrocarbons)


  -finite resource (being use faster than its being fomed)

  *Crude oil formed over millions of years due to high temperature/pressure on the remains of plants/animals

  *it is a black thick/sticky liquid found in porous rocks(under ground/sea)
• Alkanes(saturated)

  *saturated:

   they only have single carbon-carbon bonds(no double bonds)

  -form a homologous series which has the general formula CnH2n+2

  *Alkanes are generally unreactive compounds(but can combust)

  can be cracked into smaller molecules

  can react with halogens in presence of light
• Table of Alkanes

  *Methane(CH4)

  *Ethane(C2H6)

  *Propane(C3H8)

  *Butane(C4H10)

  *Pentane(C5H12)
• REVERSED

  *Methane(CH4)

  *Ethane(C2H6)

  *Propane(C3H8)

  *Butane(C4H10)

  *Pentane(C5H12)
