Questions and Answers

What does stereochemistry refer to?

  • The bonding between carbon atoms
  • The arrangement of atoms in a crystal lattice
  • The three-dimensional structure of a molecule (correct)
  • The reactivity of organic compounds

    • Why can humans metabolize starch for energy but cannot digest cellulose?

  • Because cellulose forms stronger bonds
  • Because starch has more oxygen atoms
  • Due to differences in stereochemistry (correct)
  • Due to differences in molecular weight

    • In cellulose, how does the O atom join two rings?

  • Using equatorial bonds (correct)
  • Using triple bonds
  • Using axial bonds
  • Using double bonds
