The correct Answer is:
To determine the number of moles of ethylene glycol required per mole of terephthalic acid for the formation of terylene, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Reaction**: Terylene is a polymer formed by the condensation reaction between ethylene glycol and terephthalic acid. The general reaction can be represented as: \[ n \text{(ethylene glycol)} + n \text{(terephthalic acid)} \rightarrow \text{Terylene} + n \text{(water)} \] 2. **Identifying the Molar Ratio**: From the reaction, we can see that for every mole of terephthalic acid, one mole of ethylene glycol is required. This means that the molar ratio of ethylene glycol to terephthalic acid is 1:1. 3. **Calculating Moles for One Mole of Terephthalic Acid**: Since we are asked for the number of moles of ethylene glycol required per mole of terephthalic acid, we can conclude that: \[ \text{Moles of ethylene glycol required} = 1 \text{ mole} \] 4. **Final Answer**: Therefore, the number of moles of ethylene glycol required per mole of terephthalic acid is **1 mole**. ### Conclusion: The answer is **1 mole of ethylene glycol per mole of terephthalic acid**. ---
