Questions and Answers
  • 1. 
    What is the molecular polarity of H2 and why?
    • A. 

      It is polar, because its charges are distributed asymmetrically and its geometric shape is asymmetrical.

    • B. 

      It is nonpolar, because its charges are distributed symmetrically and its geometric shape is symmetrical.

    • C. 

      It is polar, because its charges are distributed symmetrically and its geometric shape is symmetrical.

    • D. 

      It is nonpolar, because its charges are distributed asymmetrically and its geometric shape is asymmetrical.

  • 7. 
    Why does sucrose dissolve in water, while octane does not?
    • A. 

      Sucrose is a nonpolar molecule, while octane is a polar molecule. Because sucrose and water have different molecular polarities, sucrose dissolves in water.

    • B. 

      Sucrose does not dissolve in water.

    • C. 

      Sucrose is a polar molecule, like water is, while octane is a nonpolar molecule. Since sucrose and water have the same molecular polarities, based on "like dissolves like", sucrose will dissolve in water. On the other hand, octane and water do NOT have similar polarities, so octane will not dissolve in water.

    • D. 

      Sucrose is covalent, like water is.

  • 8. 
    Why is octanol more soluble in water than octane is?
    • A. 

      Octanol is a nonpolar molecule, while octane is a polar molecule. Because octanol and water have different molecular polarities, octanol dissolves in water.

    • B. 

      Octanol is a polar molecule, like water is, while octane is a nonpolar molecule. Since octanol and water have the same molecular polarities, based on "like dissolves like", octanol will dissolve in water. On the other hand, octane and water do NOT have similar polarities, so octane will not dissolve in water.

    • C. 

      Octanol is covalent, like water is.

    • D. 

      Octanol and octane have the same solubility in water.
