Questions

  1. 1.

    Which of the following statements correctly describes the relationship between the repeating unit of a condensation polymer and its constituent monomers?

    • A) The repeating unit has the exact same molecular mass and atomic composition as the sum of its reacting monomers.
    • B) The repeating unit has a lower molecular mass than the sum of the reacting monomers due to the elimination of a small molecule.
    • C) The repeating unit has a higher molecular mass than the reacting monomers due to the incorporation of atmospheric oxygen during chain growth.
    • D) The repeating unit consists exclusively of a carbon-only backbone formed by breaking carbon-carbon double bonds between monomers.
