Worked Solution & Example Answer:Water is released during a polymerisation reaction - HSC - SSCE Chemistry - Question 1 - 2010 - Paper 1
Step 1
Which monomer is likely to have been involved in the reaction?
Answer
In polymerization reactions where water is released, we are typically looking at condensation reactions, also known as step-growth polymerizations. Among the options provided:
- Ethene (A) does not release water; it undergoes addition polymerization.
- Glucose (B) undergoes condensation polymerization when it forms polysaccharides; thus, it is likely involved in a reaction that releases water.
- Styrene (C) is involved in addition polymerization and does not release water.
- Vinyl chloride (D) also undergoes addition polymerization and does not release water.
Based on this analysis, the most likely monomer involved in the reaction, releasing water, is Glucose.
