A It is a copolymer and polymerization occurs in presence of MgO .
B It is a synthetic rubber.
C It is used to prepare hose pipes for transport of gasoline.
D The monomer involved in its preparation is unsaturated.

Verified Solution

Answer & Solution

Correct Answer

(A) It is a copolymer and polymerization occurs in presence of MgO .

Step-by-step Solution

Detailed explanation

Neoprene is a synthetic rubber (elastomer), an addition polymer of chloroprene (2-chloro-1,3-butadiene). It is used to prepare hose pipes for transport of gasoline.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
