(a)
Interpretation Introduction
Interpretation:
The structure formula for portion of polymer obtained from orthophthalic acidand glycerol needs to be determined.
Concept Introduction:
A polymer is a long chain molecule made of large number of monomer units. The monomer is repeating units of a polymer that are linked to each other to produce a molecule of polymer.
These monomer units are linked to each other either through the formation of peptide linkage or glycosidic linkage or by removal of any moiety such as a water molecule.
Polyvinyl chloride, Bakelite and polystyrene are some of the example of
(b)
