Answer
Propene (C₃H₆) can react with but-1-ene (C₄H₆) to form a copolymer. This reaction is feasible as they both contain the double bond necessary for addition polymerization.
Step 2
B. but-1-ene and but-2-ene.

Answer
This pair, but-1-ene (C₄H₆) and but-2-ene (C₄H₆), can also react to form a copolymer due to their similar structure and availability of double bonds.
Step 3
C. but-1-ene and 2-ene.

Answer
This pair is not correctly defined, as '2-ene' is vague and needs specification. Thus, it cannot be definitively chosen as correct without more context.
Step 4
D. pent-2-ene and but-2-ene.

Answer
Pent-2-ene (C₅H₁₀) and but-2-ene (C₄H₆) can react together to form a copolymer as they both contain the necessary double bonds for the polymerization process.
