As we know, dimers, trimers etc. can be produced from a certain amount monomers. In the case of a dimer being produced, two monomers dimerise.
Let's take an example of a dimer (glycine anhydride):
Two glycine monomers were dimerised for this - it's a dimer since it has 2 (poly)amide bonds.
This is where my question comes in: would it not be appropriate to call ethyl ethanoate a monomer? As we saw with glycine anhydride, it has two (poly)amide bonds, hence it's a dimer. Ethyl ethanoate has a single ester bond, so would this not render it as a monomer? Or is this incorrect logic, since ethyl ethanoate isn't an oligomer/polymer per se?
P.S. I sometimes put the word 'poly' in parenthesis since I'm not sure whether its usage is necessary in description.
