Neco 2021 Chemistry Question 42
Practice objective / multiple choice question 42 from the 2021 Neco Chemistry examination.
Five point zero grams of 2‑propanol (\(\text{C}_{3}\text{H}_{8}\text{O}\)) is oxidised with excess acidified potassium dichromate according to the equation: \(3\,\text{C}_{3}\text{H}_{8}\text{O} + \text{K}_{2}\text{Cr}_{2}\text{O}_{7} + 4\,\text{H}_{2}\text{SO}_{4} \rightarrow 3\,\text{CH}_{3}\text{CO}\text{CH}_{3} + \text{Cr}_{2}(\text{SO}_{4})_{3} + \text{K}_{2}\text{SO}_{4} + 7\,\text{H}_{2}\text{O}\). Determine the theoretical mass of acetone produced and, if the actual mass obtained is 3.00 g, calculate the percent yield.
