Write the monomers which are used for the synthesis of following polymer : Polythene
Indicate the type of polymerisation for each which forms polymer.

Explanation

To solve the question regarding the synthesis of polythene (polyethylene), we will follow these steps:

### Step 1: Identify the Monomer
The monomer used for the synthesis of polythene is **ethene** (also known as ethylene). The chemical structure of ethene is represented as \( \text{C}_2\text{H}_4 \) or \( \text{CH}_2=\text{CH}_2 \).

### Step 2: Understand the Polymerization Process
Polythene is synthesized through a process called **polymerization**. Specifically, the type of polymerization used for the synthesis of polythene is **addition polymerization** (also known as chain-growth polymerization).
