The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Polythene**: Polythene, also known as polyethylene, is a type of polymer. It is important to know that polymers are large molecules made up of repeating units called monomers. 2. **Identifying the Monomer**: The monomer for polythene is ethene (or ethylene), which has the chemical formula C₂H₄. Ethene consists of two carbon atoms connected by a double bond, with each carbon atom bonded to two hydrogen atoms. 3. **Defining Polymerization**: The process by which polythene is produced is called polymerization. Polymerization involves the chemical reaction where small monomer units (like ethene) combine to form a larger macromolecule (the polymer). 4. **Mechanism of Polymerization**: During polymerization, the double bond (pi bond) in ethene breaks, allowing the carbon atoms to form single bonds with adjacent monomer units. This results in a long chain of carbon atoms, which is the structure of polythene. 5. **Conclusion**: Therefore, polythene is produced by the process of polymerization, where ethene monomers link together to form the polymer. **Final Answer**: Polythene is produced by polymerization. ---
