  1. Question 1

    Q1. A compound contains 10 grams of phenol and 20 grams of hydrogen peroxide. What is the percentage yield of the reaction?

    • A) 20%
    • B) 30%
    • C) 40%
    • D) 50%

    Answer: 30%

    Explanation: The theoretical yield of the reaction is 10 g of phenol. However, only 20 g of hydrogen peroxide is used, resulting in a yield of 10 g * (20 g / 40 g) = 5 g. The percentage yield is (5 g / 10 g) * 100% = 50%, which is approximately 30%.
