  • Question
  • Which statement about weak bonds is correct?


  • Options
  • A. Covalent bonds are weak bonds
  • B. They are hard to break
  • C. Weak bonds are transient and easily reversible.
  • D. All of the above

  • Correct Answer
  • Weak bonds are transient and easily reversible. 

    Explanation

    In chemistry, Weak bonds are those forces of attraction that, do not take a large amount of energy to break.

     

    For example, hydrogen bonds are broken by energies in the order of 4 - 5 kcal/mol.

    Ionic bonds, hydrogen bonds and van der Waals interactions are considered weak bonds.

     

    Weak bonds are transient and easily reversible.
