(a)
Interpretation:
The monomer for polyethylene needs to be determined.
Concept introduction:
The monomer units combined together to form
Explanation of Solution
The structure of polyethylene polymer is as follows:
From the above structure, it can be seen that the repeating units are:
Thus, the monomer for the given polymer is ethylene.
(b)
Interpretation:
The monomer for polyethylene terephthalate needs to be determined.
Concept introduction:
The monomer units combined together to form polymer in the polymerization reaction. There are two types: addition and condensation polymerization.
Explanation of Solution
The structure of polyethylene terephthalate polymer is as follows:
From the above structure, it can be seen that the polymer is formed using two monomers and the formation of polyethylene terephthalate is represented as follows:
Thus, the monomers for the given polymer are dimethyl terephthalate and ethylene glycol.
(c)
Interpretation:
The monomer for polytetrafluoroethylene needs to be determined.
Concept introduction:
The monomer units combined together to form polymer in the polymerization reaction. There are two types: addition and condensation polymerization.
Explanation of Solution
The structure of polytetrafluoroethylene polymer is as follows:
From the above structure, it can be seen that the repeating units are:
Thus, the monomer for the given polymer is tetrafluoroethylene.

Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forward
