plastics + polymers

Question 1

Define polymers

Answer 1

large organic Molecules made up of hundreds / thousands of atoms

Substance that has a molecular structure built from similar units (monomers) bonded together

Question 2

plastics

Answer 2

Synthetic(manmade ) polymers

Question 3

Macromolecule

Answer 3

molecule containing a large number of atoms

Question 4

monomer?

Answer 4

a molecule that can be bonded to other identical to form a polymer molecule

Question 5

The type of polymerisation depends on the functional group of the monomers reacting . what arethe types of polymerisation?

Answer 5

Addition and condensation Polimerisation

Question 6

Addition polymerisation

Answer 6

addition reaction in which two or more Molecules join to form a single product molecule

Question 7

Formation of polyethene

Answer 7

> ethene monomers
double bonds break → 2 free radicals
free radicals quickly bond→ reaction repeats until very long chain forms

Question 8

Identification of monomers from polymer

Answer 8

> find repeating unit and bracket it
separate and Put doubllbond
name the monomer -
