  1. What is a covalent bond?
    A covalent bond is when valence electrons are shared
  2. How many covalent bonds will C always form?
    Carbon will always form 4 covalent bonds.
  3. When a carbon-carbon bond is broken and then a new more stable partnership is formed, what is released?
    Energy is released when carbon FORMS new bonds(partnerships)
  4. What is the name of compounds consisting of only carbons and hydrogens?
    A compound consisting of only carbons and hydrogens is a hydrocarbon.
  5. What does it mean to be a saturated hydrocarbon?
    A saturated hydrocarbon has only single bonds between the carbons
  6. What does it mean to be an unsaturated hydrocarbon?
    An unsaturated hydrocarbon has one or more double bonds between the carbons.
  7. As the number of carbon atoms increases, the boiling point ____.
    As the number of carbon atoms increases, the boiling point increases.
  8. What does the molecular formula give us about a compound?
    The molecular formula give us the number of atoms in a compound?
  9. What does the structural formula give us about a compound?
    The structural formula give us the geometry or 3D arrangement of the cmpd

    A) molecular formula
    B) condensed formula
    C) structural formula
    B) condensed formula
    (this multiple choice question has been scrambled)
  11. How many carbons does the prefix prop- indicate?
    The prefix prop- means 3 Carbons
  12. How many carbons does the prefix eth- indicate?
    The prefix eth- means 2 carbons
  13. How many carbons does the prefix but- indicate?
    The prefix but- means 4 carbons
  14. What is the general formula for an alkane?
    The general formula for an alkane is CnH2n+2
  15. What is the general formula for an alkene?
    The general formula for an alkene CnH2n
  16. Is this molecule an alkene, alkane or alkyne: C5H12
    C5H12 is an alkane
  17. Is this molecule an alkene, alkane or alkyne: CH3CH2CH2CHCH2
    CH3CH2CH2CHCH2 is an alkene
  18. What type of bonds do alkynes have?
    Alkanes have triple bonds (or unsaturated)
  19. What type of structure does a benzene molecule form?
    Benzene forms a 6 C ring structure with alternating single/double bonds.
  20. Due to the bond angle of C - H, what geometric shape is formed?
    Tetrahedron is the 4 sided figure formed when C bond to H
  21. Are organic molecules generally polar or nonpolar? Why?
    Organic molecues are generally nonpolar due to thier symmetry.
  22. Give an example of a polar molecule
    an example of a polar molecule is water
  23. Generally, are organics soluble in water? Why?
    Generally organics are not soluble in water because organics are nonpolar and water is polar.
  24. What organics can be soluble in water? What about thier structure makes this possible?
    Organic alcohols can be soluble in water due to the polar -OH group
  25. Compare the melting point of an organic cmpd to an inorganic cmpd
    Genrally, organic cmpds have lower melting points than inorganics.
  26. Compare the reaction time of organics to inorganics
    Generally, the reaction time is slower for organic cmpds due to the covalent bonds
  27. For what does IUPAC stand?
    IUPAC stands for International Union of Pure and Applied Chemists
  28. As the number of carbons in a hydrocarbon chain increase, the melting point _____.
    As the number of carbons in a hydrocarbon chain increase, the melting point INCREASES
