WebChemguide questions 3. This question concerns the substitution of hydrogen by chlorine in the methyl group of methylbenzene. If you haven't actually needed to read the page about methylbenzene, try it anyway. That's why you are learning about mechanisms so that you can work out what would happen in an unfamiliar case. WebThis polymer can be represented by the following repeating unit: The overall equation can be represented as: The monomer units are linked together by the ester group: Polymers containing this type of linkage are therefore known as polyesters. The above polymer is known as terylene. It is used in fire-resistant clothing (eg racing drivers)
