Break Down the Problem

1. Identify the reactants and products in the given chemical equation:
   • Reactants: C2Cl4 (tetrachloroethylene) and Cl2 (chlorine gas)
   • Product: C2Cl6 (hexachloroethane)

Relevant Concepts

2. Understand the types of chemical reactions:
   • Synthesis Reaction: When two or more reactants combine to form a single product.
   • Single Replacement Reaction: One element replaces another in a compound.
   • Double Replacement Reaction: Two compounds exchange components to form two new compounds.
   • Combustion Reaction: A substance combines with oxygen, releasing energy.

Analysis and Detail

3. Analyze the reaction:
   • The reactants C2Cl4 and Cl2 are combining to form the product C2Cl6. There is no element replacement or exchange occurring; rather, the chlorine molecule is adding onto the carbon compound.
   • This indicates a synthesis reaction, as two or more reactants are producing a single product.

Verify and Summarize

4. Confirm the classification:
   • C2Cl4 and Cl2 are combining without replacement or exchange, affirms that this is indeed a synthesis reaction.
   • Therefore, the correct answer is synthesis.

Final Answer

The reaction represented by the equation $\text{C}_2\text{Cl}_4 + \text{Cl}_2 \rightarrow \text{C}_2\text{Cl}_6$ is a synthesis reaction.
