Explanation:
Acetylene undergoes linear polymerization to form a polymer when passed through a solution of cuprous chloride in ammonium chloride. The process involves the union of multiple acetylene molecules to form a single polymer molecule. Let's break down the process to understand why 3 acetylene molecules unite to form a polymer molecule.
1. Initiation:
- The cuprous chloride in the solution acts as a catalyst to initiate the polymerization reaction.
- It reacts with acetylene molecules to form vinyl copper complex intermediates.
2. Propagation:
- The vinyl copper complex reacts with another acetylene molecule to form a longer chain intermediate.
- This process continues as more acetylene molecules add to the chain.
3. Termination:
- The polymerization process stops when there are no more reactive sites available on the chain intermediates.
- The final polymer molecule consists of a chain of acetylene units linked together.
Reason for 3 acetylene molecules:
- In the case of acetylene polymerization, each vinyl copper complex reacts with two acetylene molecules to form a longer chain intermediate.
- Therefore, to form a complete polymer molecule, 3 acetylene molecules are required - 2 acetylene molecules to add to the vinyl copper complex and 1 acetylene molecule to complete the chain.
Therefore, 3 acetylene molecules unite to form a molecule of the polymer in the linear polymerization process involving cuprous chloride in ammonium chloride solution.

Acetylene undergoes linear polymerisation reaction when passed through a solution of cuprous chloride in ammonium chloride to give vinylacetylene and divinylacetylene.
This is correct as 3 molecules are involved in polymerisation.
