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...
