  1. What is the chemistry of carbon and carbon containing compounds?
    Organic chemistry
  2. What is the chemistry of those things derived from living or once living things?
    Organic chemistry
  3. Number of inorganic compounds?
    Thousands
  4. Number of organic compounds?
    Millions
  5. Flammability of inorganic compounds
    most are not
  6. Flammability of organic compounds
    most are
  7. Melting point of inorganic compounds
    most are high
  8. Melting point of organic compounds
    most are low
  9. solubility of inorganic compounds in water
    soluble
  10. solubility of organic compounds in water
    insoluble
  11. type of bonding of inorganic compounds
    ionic
  12. type of bonding of organic compounds
    covalent
  13. chemical reactions of inorganic compounds

  14. chemical reactions of organic compounds
    react between molecules
  15. complexity or inorganic compounds
    simple
  16. complexity or organic compounds
    complex
  17. size and number of atoms of inorganic compounds
    small with few atoms
  18. size and number of atoms of organic compounds
    large with many atoms
  19. Why does a molecular formula not tell us enough about an organic compound to give it a name?
    1. because it doesn't tell us anything about the arrangement of the atoms

    2. the exact arrangement is very important in identifying an organic substance
  20. multiple organic compounds with the same elements and the same number of atoms of each element but entirely different physical and chemical properties are calle what?
    isommers
  21. organic compounds with the same molecular formula but different structural formulas are called what?
    isomers
  22. a diagram showing the exact arrangment and bonding patterns of an organic compound is called what?
    a Structural formula
  23. How many bonds does a carbon atom have?
    4
  24. How many bonds does a hydrogen atom have?
    1
  25. How many bonds does a nitrogen atom have?
    3
  26. How many bonds does an oxygen atom have?
    2
  27. Why is carbon able to bond in so many different ways?
    because of its tetrahedral shape
  28. an abbreviation of a structural formula that combines the use of symbols and subscripts as in molecular formulas with the use of repeated symbols as in structural formulas, is called?
    Line formula

    or

    Semi-structural formula
  29. Alk
    aliphatic hydrocarbon
  30. Meth
    one carbon chain
  31. Eth
    two carbon chain
  32. Prop
    three carbon chain
  33. But
    four carbon chain
  34. Pent
    five carbon chain
  35. Hex
    six carbon chain
  36. Hept
    seven carbon chain
  37. Oct
    eight carbon chain
  38. Non
    nine carbon chain
  39. Dec
    ten carbon chain
  40. ane
    saturated, all single bonds
  41. ene
    double bond present
  42. yne
    triple bond present
  43. yl
    side chain of carbons
  44. compounds that contain only hydrogens and carbons are called?
    hydrocarbons
  45. compounds that are bonded together in a ring formation are called?
    cyclic compounds
  46. when all carbons make up a ring of cyclic compounds they are called?
    carbocyclic compounds

    they are considered hydrocarbons
  47. compounds with mostly carbons in the ring but something else present also are called?
    Heterocyclic compounds

    they are NOT considered hydrocarbons

    forms a different type of cyclic compound
  48. organic compounds bonded in an open chain formation are called?
    Acyclic compounds

    or

    Aliphatic compounds
  49. when there are all singe covalent bonds between carbons, aliphatic compounds are called
    alkanes
  50. when there is at least one double covalent bond between carbons, aliphatic compounds are called
    Alkenes
  51. when there is at least one triple covalent bond between carbons, aliphatic compounds are called
    Alkynes
  52. Are alkanes saturated or unsaturated? And why?
    Saturated. They are holding as many hydrogens as possible
  53. Are alkenes saturated or unsaturated? And why?
    Unsaturated. They could hold more hydrogens.
  54. Are alkynes saturated or unsaturated? And why?
    Unsaturated. They could hold more hydrogens.
  55. What is the characteristic type of bond for the alkynes?
    addition
  56. What is the characteristic type of bond for the alkenes?
    addition
  57. What is the characteristic type of bond for the alkanes?
    replacement

    side chain
  62. What are the simplest of the organic compounds?

    butene
  67. What is the shape of a carbon atom?
    tetrahedral
  68. Why did the structural formula have to be devised?
    Because of isomers; a new formula had to be created to show the elements involved and how many atoms of each as well as the arrangement of the atoms.
  69. Why does a molecular formula not tell us enough about an organic compound to give it a name?
    • 1. because it doesn't tell us anything about the arrangement of the atoms
    • 2. the exact arrangement is very important in identifying an organic substance
