What is the degree of polymerization (DP)?
Correct answer: C. The number of repeating units in the chain
- A. The total molecular mass of the polymer
- B. The number of monomers in the polymer
- C. The number of repeating units in the chain
- D. The molecular mass of a single monomer
Explanation
The correct answer is Option C: The degree of polymerization (DP) refers to the number of repeating units in a polymer chain. It is an important parameter that determines the molecular weight and properties of the polymer. Option A is incorrect because it describes the total molecular mass, not the count of repeating units. Option B is misleading as it mentions 'monomers', which are the initial building blocks, but DP specifically counts the repeating units formed after polymerization. Option D refers to the molecular mass of one monomer, which is unrelated to the concept of DP.
