The idea

What is Polymers and plastics?

Polymers and plastics are giant molecules made by joining many small units called monomers into long chains. Addition polymers such as polythene and PVC form when alkene monomers open their double bonds and link up with nothing lost. Condensation polymers such as nylon and polyester form when two different monomers join with the loss of a small molecule, usually water. Chain length, branching and cross-linking decide whether a plastic is soft and flexible or rigid, and whether it softens when heated or sets permanently.

Where it appears: Class 10 and 12 CBSE and ICSE, GCSE and A-level, IB Chemistry, JEE and NEET.

Where learners get stuck

Why Polymers and plastics is hard

Learners struggle to draw the repeat unit from a monomer or recover the monomer from a polymer, and they confuse addition with condensation polymerisation when water is lost.

The picture a good explanation starts with: Several ethene molecules in a row with their double bonds opening into single bonds that link neighbours, forming a long chain with the repeat unit bracketed.

A lesson, step by step

How a lesson on Polymers and plastics goes

  1. 01

    Ask

    Type or say "How do I draw the repeat unit of a polymer?" in your own words, in any of 26 languages.

  2. 02

    Plan

    The tutor plans a storyboard, one picture per idea, starting with several ethene molecules in a row with their double bonds opening into single bonds that link neighbours, forming a long chain with the repeat unit bracketed.

  3. 03

    Explain

    It explains Polymers and plastics out loud while the picture builds step by step, pitched to your level (Class 10 and 12 CBSE and ICSE and up).

  4. 04

    Interrupt

    Say "wait, why?" or type a doubt: it stops, answers over the picture, and carries on. Ask for a different explanation any time.

  5. 05

    Check

    A checkpoint question makes sure the idea landed, and Tests keep the practice going.

  6. 06

    Your notes

    Upload a PDF or a photo of your class notes or a past paper and the lesson follows your textbook's terms.

Ask it anything

Questions learners ask about Polymers and plastics

  • How do I draw the repeat unit of a polymer?
  • What is the difference between addition and condensation polymers?
  • Why are some plastics recyclable and others not?

Any of these, or your own, typed or spoken. The tutor answers on the picture and adapts to how well you are following.

Questions

Asked, Answered

Can LetMeTeach explain Polymers and plastics?

Yes. Ask in your own words and the tutor plans a lesson on Polymers and plastics: it starts with several ethene molecules in a row with their double bonds opening into single bonds that link neighbours, forming a long chain with the repeat unit bracketed. Then it explains each step out loud as the picture builds, stops when you say "wait, why?", and ends with a checkpoint question.

Where does Polymers and plastics come up?

Class 10 and 12 CBSE and ICSE, GCSE and A-level, IB Chemistry, JEE and NEET. The lesson is pitched to your level and the exam or curriculum you follow, and you can upload your own notes or past papers so it uses your textbook's terms.

Can I learn Polymers and plastics in my own language?

Yes. LetMeTeach teaches in 26 languages and plans the lesson in the language you choose rather than translating an English one, so the terms match what your textbook says. The Free plan includes 7 hours a month with no card.
