Question
The process of forming a polymer from monomers is called polymerization. Polymerization is achieved through condensation reactions. Which of the following is true concerning the energy requirements of condensation reactions?
Question 2 options:
A) condensation reactions do not require the input of energy because they result in the formation of covalent bonds between monomers and result in the liberation of water
B) the covalent bonds generated by condensation reactions are easily broken by water and thus do not require the input of energy
C) formation of covalent bonds during condensation reactions requires an input of energy because of the associated increase in entropy in the polymer
D) formation of polymers from monomers results in a decrease in entropy and therefore requires an input of energy
Explanation / Answer
The following is true concerning the energy requirements of condensation reactions:
C) formation of covalent bonds during condensation reactions requires an input of energy because of the associated increase in entropy in the polymer
Synthesis of polymer from monomer is a spontaneous reaction and therefore associated with an increase of entropy that is randomness of the reaction.
