Question

Which among following statements is NOT true for neoprene?

• A. It is resistant to petroleum
• B. It is obtained from styrene
• C. It is a synthetic rubber
• D. It is a condensation polymer

Hint:

Always pair the suffix or phonetic sound of the polymer name with its monomer counterpart. Chlo-roprene forms Neo-prene. If a statement connects Neoprene to Styrene, it is an automatic red flag.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The problem requires us to scrutinize four chemical and physical attributes of the polymer neoprene and identify the assertion that is fundamentally false.

Step 2: Detailed Explanation:
Let's assess the characteristics and synthesis details of neoprene:
Neoprene is a renowned synthetic rubber (elastomer) prized for retaining structural flexibility across a broad temperature span. Thus, statement (C) holds true.
It demonstrates superior chemical resilience and exhibits outstanding resistance to degradation from petroleum-derived oils, greases, and organic solvents. Thus, statement (A) holds true.
Regarding its polymer categorization, it can indeed be regarded as an addition polymer produced via chain-growth polymerization, though the key structural consideration lies in its monomer unit.
Neoprene is manufactured through free radical polymerization of chloroprene (2-chloro-1,3-butadiene). Styrene serves as the monomer for polystyrene or SBR (Styrene-Butadiene Rubber), not neoprene. Consequently, statement (B) is entirely incorrect.

Step 3: Final Answer:
The false claim is that it derives from styrene, which matches option (B).
