What do the monomers of these polymers look like?

look for repeating units, the first one just split in half and there are ur monomers, with a Hydrogen on the right end and a hydroxyl group on the left end of course, since theyb look like condensation polymers ie:

a) (HOOC)(NH)(CH2)4(CH3) - [Hope u understand my notation]

b) i think that whole unit is the monomer, just ad H and OH to the ends

c) what i wrote for (b) applies here aswell, methinks

very wierd Q though....

a) I think there are two monomers: (CH2)5COOH and H2N-(CH2)5
This is called peptide bonding, and the polymer formed is an amide.

b) Don't think it works like that. All these questions are to do with peptide bonding.
Again, I think there are 2 monomers.
(CH2)8 - COOH and (CH2)6- NH2

c) (CH2)10- NH2 and (CH2)10- COOH

Don't worry about these questions too much... Peptide bonding is out of the HSC syllabus.

Phew. I've never learned or experienced peptide bonding before. :(
