Activity 4D:
Discuss the following questions in pairs and write down the answers in your notebook.
(i) What is the IUPAC name for the monomer of natural rubber?
(ii) Explain the characteristics of rubber particles that prevent rubber from coagulating.
(iii) Rubber gloves are among the products made from natural rubber. Explain the characteristics of natural rubber that enable rubber gloves to be produced.
Answer:
(i) 2-metylbut-1,3-diene
(ii) Protein membrane on rubber particle is negatively charged that causes rubber particles to repel one another.
(iii)
Characteristics of natural rubber
(a) Soft solid at room temperature for easy usage.
(b) Elastic to allow gloves to be easily worn.
(c) Water resistant so that hands are protected from external elements.
