Hydrocarbons

    Cards (16)

    • What area of chemistry focuses on compounds that contain carbon?
      Organic chemistry
    • Why is carbon considered a useful element for making large compounds?
      Because each carbon atom can form four strong bonds
    • What are hydrocarbons defined as?
      Compounds formed from carbon and hydrogen only
    • What is the name of the hydrocarbon with the formula C4H10?
      Butane
    • Why is butanol not considered a hydrocarbon?
      Because it contains an oxygen atom
    • What is the simplest type of hydrocarbons called?
      Alkanes
    • What is the molecular formula for methane?
      C1H4
    • How many carbon atoms are in ethane?
      Two
    • What is the molecular formula for propane?
      C3H8
    • How do the number of carbon and hydrogen atoms change in alkanes?
      They grow by one carbon and two hydrogens each time
    • What is a homologous series in organic chemistry?
      • A group of organic compounds with similar properties
      • React in a similar way
      • Have a general formula
    • What is the general formula for alkanes?
      CnH2n+2
    • If an alkane has three carbon atoms, how many hydrogen atoms does it have?
      Eight
    • What is the molecular formula for octane, which has eight carbon atoms?
      C8H18
    • What does it mean for alkanes to be saturated compounds?
      Every carbon atom has four single covalent bonds
    • What happens to the structure of propane if one of its single bonds is changed to a double bond?
      It would no longer be classified as an alkane
