PEG is a polymer composed of which monomer?A.ethanolB.ethenolC.ethanalD.ethylene glycol
Question
PEG is a polymer composed of which monomer?
- A. ethanol
- B. ethenol
- C. ethanal
- D. ethylene glycol
Solution
To identify the monomer from which PEG (polyethylene glycol) is composed, let's analyze the options provided:
- A. ethanol - This is a simple alcohol and does not form PEG.
- B. ethenol - This is an unstable compound and does not represent the monomer for PEG.
- C. ethanal - This is an aldehyde (acetaldehyde) and not the correct monomer for PEG.
- D. ethylene glycol - This is the diol from which PEG is formed through polymerization.
Final Answer
The correct answer is D. ethylene glycol. PEG is derived from the polymerization of ethylene glycol.
