(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

(5) One of Prof Cunningham's former students wrote his doctoral dissertation about a new
technology to clean up soil contaminated by certain types of chemicals. One of the
chemicals we tested in the lab was 1,2,4,5-tetrachlorobenzene (TECB).
(a) Draw the chemical structure of 1,2,4,5-tetrachlorobenzene.
(b) When we started working on the project, we thought maybe TeCB would be de-
stroyed according to first-order kinetics, but we weren't sure. Below are two tables
of actual data that the student collected in the laboratory. The two data sets were
collected under different experimental conditions. For each of the two experiments,
determine if the disappearance of TeCB is zero-order, first-order, second-order, or
something else. Specify the value of the rate constant (ko, k1, or k2, as appropriate).
Be sure to give the right units of k!
