Hydrocarbons + alkanes

• What are hydrocarbons composed of?


  Hydrocarbons only contain hydrogen and carbon atoms.
• What type of bonds do alkanes have?

  Alkanes have all C-C single bonds.
• What is the simplest type of hydrocarbon?

  Alkanes are the simplest type of hydrocarbons.
• What are the properties of hydrocarbons as the carbon chain gets longer?

  • Hydrocarbon properties change with chain length.
  • Shorter carbon chains are more volatile.
  • Longer carbon chains have higher boiling points.
• What happens during complete combustion of hydrocarbons?

  Complete combustion occurs when there is plenty of oxygen.
• What are the waste products of complete combustion of hydrocarbons?

  The waste products are carbon dioxide and water vapor.
• What is the general equation for the complete combustion of a hydrocarbon?

  Hydrocarbon + Oxygen → Carbon Dioxide + Water.
• How do you balance the combustion equation for methane?

  CH₄ + 2O₂ → CO₂ + 2H₂O.
• What is the significance of the number of oxygen atoms in the balanced combustion equation?

  The number of oxygen atoms must balance the carbon and hydrogen from the hydrocarbon.
• What type of bond do hydrocarbons contain?

  Hydrocarbons contain single covalent bonds.
• What are the properties of organic compounds?

  • Organic compounds primarily contain carbon.
  • They can have various functional groups.
  • Their properties vary widely based on structure.
• What is viscosity in the context of organic chemistry?

  Viscosity refers to the thickness or resistance to flow of a liquid.
• Alkanes have low boiling points compared to other hydrocarbons.
• What are the first 4 alkanes?

  Methane, ethane, propane, butane.
