Worked Solution & Example Answer:Ethene may be converted into poly(ethene) - HSC - SSCE Chemistry - Question 1 - 2001 - Paper 1
Step 1
What type of reaction is this?
Answer
The conversion of ethene into poly(ethene) involves a process known as polymerisation. In polymerisation, small molecules called monomers (in this case, ethene) react to form a larger molecule (the polymer, poly(ethene)). This reaction typically involves the breaking of double bonds in the monomers, allowing them to link together in long chains, which characterizes polymerisation. Therefore, the correct answer is (D) Polymerisation.
