Worked Solution & Example Answer:Copolymers are obtained when two or more different monomers are allowed to polymerise together - VCE - SSCE Chemistry - Question 20 - 2010 - Paper 1
Step 1
Identify the Monomers
Answer
To determine the two alkenes that could react together to form the provided polymer, we first analyze the structure of the polymer. The repeating units within the polymer indicate that both monomers must contribute carbon-carbon double bonds to allow for polymerization.
Step 2
Evaluate the Options
Answer
- Propene and but-1-ene (Option A): Both have terminal double bonds that can participate in polymerization with each other.
- Propene and but-2-ene (Option B): This combination could also work since both have the capability to form attachments through their double bonds.
- But-1-ene and but-2-ene (Option C): Two different structures that can definitely polymerize together as their ends can react similarly.
- Pent-2-ene and but-2-ene (Option D): This combination is not suitable as pent-2-ene contributes a longer chain that does not fit with the existing monomer types indicated by the structure.
