  4. 4. Why must you specify a number, such as in 'but-1-ene' rather than just 'butene'?

    • A. To show how many carbon atoms are present
    • B. To show the exact position of the double bond within the chain
    • C. To show whether the compound is saturated or unsaturated
    • D. To show the total number of hydrogen atoms

  5. 5. A student is given an unknown organic compound with molecular formula C4H9COOH. Using naming rules, explain what type of compound this is and how you identified it.

    • A. It is an alkene, because it contains a 'C=C' style formula pattern
    • B. It is a carboxylic acid, because it matches the general formula CnH2n+1COOH with the -COOH functional group
    • C. It is an alcohol, because it contains oxygen atoms
    • D. It is an alkane, because it has no functional group shown
