Step 1
Identify the Monomers
Answer
To determine the two monomers from the given polymer structure, we need to analyze the functional groups and the structure. The polymer is formed by the condensation reaction of two distinct monomers, which likely include a carboxylic acid and an alcohol.
The structure displays specific groups suggesting:
- One part has a carboxylic acid functional group (-COOH) attached to a phenolic structure (benzene with an -OH group).
- The other part also shows a carboxylic acid group, indicating that it must come from a similar aromatic compound.
Therefore, the correct two monomers can be conclusively identified from the analysis of the provided options.
Step 2
Choose the Correct Option
Answer
Among the options presented, option C is determined to be correct, as it features:
- A benzene ring with a carboxylic acid group and an -OH group.
- Another compound with a benzene ring and a hydroxyl group.
The option aligns well with the recognized structure of the polymer, ensuring both monomers are utilized effectively in forming the polymer chain.
