Cards (106)

  • What are polymers and giant covalent structures primarily composed of?
    They are made of covalent bonds.
  • Why would it be marvelous if only simple molecular substances had covalent bonds?
    Because it would simplify chemical interactions.
  • What do polymers consist of?
    Long chains of repeating units.
  • How are the atoms in a polymer connected?
    By strong covalent bonds.
  • What can you draw instead of a whole long polymer molecule?
    The shortest repeating section called the repeating unit.
  • What is the molecular formula of a polymer made of ethene?
    (CH2CH_2)
  • How do intermolecular forces between polymer molecules compare to those between simple covalent molecules?
    They are larger in polymers.
  • What does it mean that most polymers are solid at room temperature?
    They have strong intermolecular forces.
  • How do the intermolecular forces in giant covalent structures compare to those in polymers?
    They are stronger than in polymers.
  • What do giant covalent structures consist of?
    Atoms bonded by strong covalent bonds.
  • What is a characteristic of the melting and boiling points of giant covalent structures?
    They have very high melting and boiling points.
  • Why do giant covalent structures require a lot of energy to break bonds?
    Because they have strong covalent bonds.
  • What do giant covalent structures not contain?
    Charged particles.
  • Why don't giant covalent structures conduct electricity?
    They don't contain charged particles.
  • How do the properties of giant covalent structures affect their applications?
    They are used in materials needing high strength.
  • What is a key feature of the atoms in giant covalent structures?
    They are bonded strongly to each other.
  • How do the melting and boiling points of giant covalent structures compare to those of simple covalent molecules?
    Giant covalent structures have much higher points.
  • What is the significance of the lack of charged particles in giant covalent structures?
    It explains their inability to conduct electricity.
  • What type of molecules do giant covalent structures not conduct electricity?
    Charged particles.
  • Why do giant covalent structures have high melting and boiling points?
    Due to strong covalent bonds between atoms.
  • How do the properties of giant covalent structures influence their use in industry?
    They are ideal for high-strength applications.
  • What is the relationship between the strength of covalent bonds and the energy required to break them?
    Stronger bonds require more energy to break.
  • Why are polymers generally solid at room temperature?
    Because of strong intermolecular forces.
  • What does the presence of strong covalent bonds in giant covalent structures imply about their physical state?
    They are typically solid at room temperature.
