WebbStraight-chain alkanes are able to pack and layer each other better than their branched counterparts. This allows greater intermolecular forces, which raises the melting point since it will take more energy to disperse the molecules into a liquid. WebbPolymers are large molecules made up of atoms joined together by strong covalent bonds. The intermolecular forces between polymer molecules are much stronger than in small molecules because the molecules are larger. This is why most polymers are solid at room temperature.
