Polymers — practice question

PET is a polyester and also a condensation polymer. Figure 7.1 shows the two monomers needed to form PET: one dicarboxylic acid monomer and one diol monomer.
(a)[2]

Name the two monomer types shown in Fig. 7.1.

(b(i))[1]

The two monomers react to produce PET and a small molecule. Name the small molecule.
