Identify the type of polymerization reaction. (1 mark) Your answer 5. WebSilicones are synthetic polymers with a silicon-oxygen backbone similar to that in silicon dioxide (silica), but with organic groups attached to the silicon atoms by C-Si bonds. The silicone chain exposes organic groups to the outside. Thus, despite having a very polar chain, the physical properties of silicones are similar to those of an alkane. cordless capability for intertel phone

In an ethene molecule, CH 2 =CH 2, the two pairs of electrons which make up the double bond aren't the same. One pair is held securely on the line between the two carbon nuclei in a bond called a sigma bond. The other pair is more loosely held in an orbital above and below the plane of the molecule known as a π bond.
