Neco 2020 Chemistry Question 14
Practice objective / multiple choice question 14 from the 2020 Neco Chemistry examination.
5.00 g of a mixture of cyclohexanol \(C_{6}H_{12}O\) and 1‑hexanol \(C_{6}H_{14}O\) is oxidised with excess acidic \(K_{2}Cr_{2}O_{7}\) under reflux, converting each alcohol to the corresponding carbonyl compound (cyclohexanone and hexanal). After work‑up, 4.90 g of carbonyl products are obtained. Assuming 100 % yield for each oxidation, calculate the mass percent of cyclohexanol in the original mixture.
