The correct Answer is:
To determine what Z is in the given reaction, we can break down the process step by step. ### Step-by-Step Solution: 1. **Identify the Reactants**: The reactant is sodium propionate, which is represented as CH₃-CH₂-CO₂Na. This is the sodium salt of propionic acid. 2. **Understand the Reaction Conditions**: The reaction occurs in the presence of NaOH (sodium hydroxide) and CaO (calcium oxide) with heat. This indicates that we are likely dealing with a decarboxylation reaction. 3. **Decarboxylation Process**: When sodium propionate reacts under these conditions, decarboxylation occurs. This means that a carbon dioxide molecule (CO₂) is released from the sodium propionate. 4. **Formation of the Product**: After the removal of CO₂, the remaining structure is CH₃-CH₂- (which corresponds to ethane, C₂H₆). Therefore, the product formed is ethane. 5. **By-products**: Along with ethane, sodium carbonate (Na₂CO₃) is also formed as a by-product of the reaction. 6. **Final Answer**: Therefore, Z in the reaction is ethane (C₂H₆). ### Summary: The final product Z is ethane (C₂H₆).
