  1. Recall the difference between alkanes and other hydrocarbons (alkenes and alkynes).
    Look at the following molecular formulae and identify which formulae show alkanes.
    i) C2_2H4_4
    ii) C4_4H10_{10}
    iii) C3_3H6_6
    iv) C10_{10}H22_{22}
    v) CH4_4
    vi) C2_2H2_2
    1. Apply the rules of organic nomenclature to branched and unbranched alkanes.
      From the descriptions, suggest the IUPAC systematic name of the following compounds:
      1. An alkane with 6 carbons in the main chain, and a 1 carbon branch at the 3rd carbon.
      2. An alkane with 4 carbons in the main chain, and a 1 carbon branch at the 2nd carbon.
      3. An alkane with 8 carbons in the main chain, and a 2 carbon branch at the 3rd carbon.
      4. An alkane with 5 carbons in the main chain with the two end carbons bonded together.
    2. Draw the structural formula of simple branched, unbranched and cyclic alkanes.
      Use the IUPAC systematic names of the compounds below to draw their structural formula.
      1. 2-methylhexane.
      2. Heptane.
      3. Methylpropane.
      4. 3-ethyloctane.
      5. Methylcyclohexane.
      6. 1-ethyl-2-methylcyclohexane.
