  1. Question 1

    Q1. A compound contains 25 grams of phenol and 10.2 grams of sodium hydroxide. What is the percentage yield of the reaction?

    • A) 50%
    • B) 55%
    • C) 60%
    • D) 65%

    Answer: 55%

    Explanation: The theoretical yield of the reaction is 25 g of phenol. However, only 10.2 g of sodium hydroxide is used, resulting in a yield of 25 g * (10.2 g / 25 g) = 20.4 g. The percentage yield is (20.4 g / 25 g) * 100% = 81.6%, which is approximately 80%.
