Hi, I was wondering on this paper on question 4, how is the answer D? Surely it would be C as this could form condensation polymer with itself with H2O molecules being eliminated? Also, does condensation polymerisation only apply when a molecule of H2O is removed, not any other molecules e.g. HCl?

Condensation polymerisation is carried out between two different functional groups.

in D, you have an acyl chloride group reacting with an amine group https://www.chemguide.co.uk/organicp.../nitrogen.html

Condensation polymerisation doesn't have to only produce water, any small molecule is a valid byproduct.
