This question is about monomers and polymers.

Compound X is ethyl acrylate, which possesses both an alkene functional group and an ester functional group.

The displayed formula of Compound X is shown below:

Displayed formula of Compound X (ethyl acrylate). On the left, there is an alkene group featuring a H2C=CH- unit. The CH carbon is single-bonded to a carbonyl carbon (C=O). This carbonyl carbon is single-bonded to an oxygen atom, which is in turn single-bonded to an ethyl group (-CH2-CH3).

a.
