Neco Model Questions Vol1 2021 Chemistry Question 5
Practice objective / multiple choice question 5 from the 2021 Neco Model Questions Vol1 Chemistry examination.
A mixture contains 10.0 g of cyclohexanol (\(\mathrm{C_6H_{11}OH}\), \(M = 100.16\ \text{g mol}^{-1}\)) and 8.0 g of 2‑methyl‑1‑propanol (\(\mathrm{C_4H_{10}O}\), \(M = 74.12\ \text{g mol}^{-1}\)). The mixture is oxidised with excess potassium dichromate in acidic medium. Secondary alcohols are oxidised to ketones and primary alcohols to carboxylic acids. Assuming an overall isolated‑yield of 85 % for each oxidation, calculate (a) the mass of cyclohexanone formed and (b) the mass of 2‑methylpropanoic acid formed.
