Question 1
Ethene may be converted into poly(ethene). What type of reaction is this? (A) Condensation (B) Hydrolysis (C) Oxidation/reduction (D) Polymerisation
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) is a process known as polymerisation. In this reaction, multiple monomer units (in this case, ethene) chemically bond together to form a large molecule, or polymer. This type of reaction is characterized by the linking of small repeat units, which significantly increases the molecular weight and changes the material's properties.
Therefore, the correct answer is (D) Polymerisation.
