Expert Answer:

Entire chapter is important. Please go through the NCERT questions, live test series, model tests, and chapter tests to make the concepts more understandable. For this log on to http://new.topperlearning.com/

Hopwever, you can refer to the following questions:

  • Write the names of monomers of the following polymers:

(i) Nylon 6,6 (ii) Neoprene (iii) Buna –NPolymerisation and its classification with example.

  • Types of polymers on the basis of structure.
  • Differentiate between homopolymer and co-polymer with example?
  • Write short note on:

a) Condensation polymer

b) Addition polymer

c) Elastomer

d) Fibres

e) Teflon

  • Differentiate between thermoplastic polymers and thermosetting polymers with examples.(important)
  • Define a copolymer, thermoplastics, Polymer, homopolymer, copolymer
  • Explain the free radical mechanism from chain initiating step to chain terminating step.
  • Show how the low density and high density polythene is made. (very important)
  • Bakelite and its importance.
  • The process of co-polymerisation.
  • A short note on rubber and its vulcanization. (very important)
  • Explain the difference between Buna-N and Buna-S.
  • How is dacron obtained from ethylene glycol and terephthalic acid?
  • Identify the monomer in the following:

(Structures will be provided)

  • How does the presence of double bonds in rubber molecules influence their structure and reactivity? (very important)
  • Complete the following reaction:

(Reactions will be provided)

  • What are the monomeric repeating units of Nylon-6 and Nylon-6,6?
  • How can you differentiate between addition and condensation polymerization.

To learn the structures you need to practice them daily.
