Question

1. (a) What functional groups are present in (i) PET, (ii) Nylon and (iii) adipoyl chloride ?
2. 2. These three functional groups in question 1(a) are part of a larger family of functional groups. What is that larger family ?
   3. C. The larger family of functional groups in question 1(b) typically undergo reactions of a common general mechanistic pathway. The hydrolysis of PETE and the formation of Nylon in this experiment are both examples of this. What is the name of type of mechanism ?
3. 2- Industrially, nylon-6,6 is made by heating a diamine with a dicarboxylic acid. In a laboratory setting, it is difficult to make nylon using this method due to the formation of another product. Provide an equation to show this reaction.
4. 3- Polyesters can be made using the acid catalysed reaction of carboxylic acids and alcohols. Draw the curly arrow mechanism for this reaction by showing how methanoic acid and ethanol react to give ethyl methanoate.
