I include them just out of interest and to show that it would be difficult to do this in a school lab! Half of each double bond is broken, and the electrons are used to join on … But in the lab, we normally avoid using dangerous liquid bromine and instead … This is exactly like the polyester repeat unit and chain except that the single-bonded … WebThe student first mixes phenylethene with excess bromine at room temperature. An organic compound forms with the molecular formula C 8H 8Br 2. ... Draw the repeat unit of nylon-4,6. Clearly display the bonding that links the two monomers. [2] (c) A sample of a protein is hydrolysed. The organic products are separated by chromatography.
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. Web1.

WebHowever, the name of the repeating unit could be based on its source, poly (ethenylbenzene), or, on the structure of the polymer, poly (1-phenylethane-1,2-diyl). Luckily, some well-established common names, like polystyrene, are still acceptable. WebAug 25, 2015 · 1. Poly (phenylethene), commonly known as polystyrene, is the third most important polymer, in terms of amount made from ethene. Its physical properties can be adjusted to suit a range of everyday uses. Techniques have been developed which increase its mechanical strength, its ability to absorb shock and its thermal insulating properties.
