GCSE Chemistry Revision "Bonding in Polymers"
Freesciencelessons・3 minutes read
Polymers are large molecules created by joining monomers, with strong covalent bonds and intermolecular forces giving them a high melting point. The structure involves bond changes from double to single covalent bonds, represented by repeating units, with strong intermolecular forces solidifying most polymers at room temperature.
Insights
- Polymers are created by linking numerous identical small molecules known as monomers, like ethene forming polyethene. The strong covalent bonds and intermolecular forces in polymers result in a high melting point, rendering them solid at room temperature.
- The structure of polymers involves converting double covalent bonds in monomers to single bonds in the polymer, leading to the formation of large molecules with repeating units. This process, combined with robust intermolecular forces, contributes to the solid nature of most polymers at room temperature due to their high melting point.

"Polymer Structure: Strong Bonds, High Melting Point"
- Polymers are large molecules formed by joining thousands of small identical molecules called monomers, often alkenes. For example, ethene molecules can join to create polyethene, with double covalent bonds in monomers and single covalent bonds in the polymer. Represented by a repeating unit, polymers have strong covalent bonds and intermolecular forces that give them a high melting point, making them solid at room temperature.
- The structure and bonding in polymers involve the formation of large molecules from monomers, with specific bond changes from double to single covalent bonds. Polymers are represented by repeating units, showcasing the extension of covalent bonds and a large number of repeating units. The intermolecular forces between polymer molecules are strong, leading to a high melting point and the solid state of most polymers at room temperature.
