  • What elements are present in hydrocarbons?
    Hydrocarbons contain only carbon and hydrogen atoms.
  • What does 'hydro' mean in organic chemistry?
    'Hydro' refers to hydrogen, not water, in organic chemistry.
  • How many bonds must a neutral carbon atom make?
    A neutral carbon atom must make four bonds.
  • What is the difference between alkanes, alkenes, and alkynes?
    Alkanes have only single bonds, alkenes have at least one double bond, and alkynes have at least one triple bond between carbons.
  • What is the prefix for a hydrocarbon with three carbons?
    The prefix for three carbons is 'prop'.
  • What is the general formula for alkanes?
    The general formula for alkanes is CnH2n+2, where n is the number of carbons.
  • What does 'saturated hydrocarbon' mean?
    A saturated hydrocarbon has the maximum number of hydrogens attached to each carbon, as in alkanes.
  • What is the hybridization of carbon atoms in alkanes?
    Carbons in alkanes are sp3 hybridized.
  • What is the general formula for alkenes with one double bond?
    The general formula for alkenes with one double bond is CnH2n.
  • Why do alkenes have fewer hydrogens than alkanes?
    Alkenes lose two hydrogens for each double bond because carbon cannot make more than four bonds.
  • What is the general formula for alkynes with one triple bond?
    The general formula for alkynes with one triple bond is CnH2n-2.
  • What is the hybridization of carbons in alkynes?
    Carbons involved in a triple bond in alkynes are sp hybridized.
  • What is the major structural feature of aromatic hydrocarbons?
    Aromatic hydrocarbons contain a benzene ring, which is C6H6.
  • What is a resonance hybrid in benzene?
    A resonance hybrid is a composite structure representing all possible resonance forms of benzene, often shown as a circle inside the ring.
  • Where can benzene rings be found in everyday life?
    Benzene rings are found in fossil fuels, gasoline, and some medications like Lipitor.
