Question

Ethene units join together to form


​

Answer 1

Answer:

The reaction is called a polymerisation reaction:

ethene is the monomer

poly(ethene) is the polymer

The C=C double bond in ethene is involved in the polymerisation reaction. It allows ethene molecules to join together to form a single product, so it is an example of an addition reaction. Poly(ethene) is an addition polymer.

Modelling addition polymers

It is too difficult to model a complete addition polymer molecule, as it contains many atoms. Instead, we show the structure of its repeating unit, the part that is repeated many times. To deduce the structure of a polymer from the monomer:

Draw the structure of the monomer but use C–C instead of C=C.

Draw brackets around the structure with a long bond passing through each one.

The table shows the structure of ethene and its polymer.

Answer 2

Answer:

the chemical process of joining monomeric units together to form a polymer is termed polymerization.
