A key difference between addition and condensation polymerization is that addition polymerization:
Correct answer: C. Does not involve the elimination of a small molecule
- A. Eliminates a water molecule
- B. Involves reaction between two functional groups
- C. Does not involve the elimination of a small molecule
- D. Is generally ionic in nature
Explanation
Addition polymerization involves the joining of monomers without the formation of by-products, such as water or other small molecules. This is in contrast to condensation polymerization, where the reaction between functional groups results in the elimination of small molecules like water. Thus, the key difference highlighted in the question is the absence of small molecule elimination in addition polymerization. Options A and B describe characteristics of condensation polymerization, while Option D incorrectly states that addition polymerization is ionic in nature. The correct answer is Option C.
