is a synthetic polymer classified as plastics.

Polyethylene

A carbonate

Kevlar

A nucleotide

Polythene

Polythene is a synthetic polymer classified as plastics.

Explanation:

Polythene is formed artificially from several repeating units of ethene molecules (monomers) in a reaction known as polymerization.

The polyethene can be represented as [CH2-CH2]n, where n is thousands to ten thousands unit of ethene.

It is used to make

- plastic bags,

- cable insulators

- plastic crates etc

Thus, polythene is a synthetic polymer of ethene, and classified as plastics.

Polyethylene

Explanation:

They are man made polymers consisting of several long chain monomers of the same chemical composition. It has a chemical formula of (C2H4)n where n is the number of units or chain.

It is the most popular synthetic polymer due to its easy, simple structure and lightweight compared to other synthetic polymers produced commercially.

It is used in making grocery bags, automobile parts etc.
