Neco Model Questions Vol1 2022 Chemistry Question 5
Practice objective / multiple choice question 5 from the 2022 Neco Model Questions Vol1 Chemistry examination.
A 12.0 g sample of a mixture of 1‑butanol (\(\mathrm{C_4H_{10}O}\)) and 2‑butanol (\(\mathrm{C_4H_{10}O}\)) is oxidised with excess potassium dichromate in acidic medium. The oxidation converts 1‑butanol to butanoic acid (\(\mathrm{C_4H_8O_2}\)) and 2‑butanol to butan‑2‑one (\(\mathrm{C_4H_8O}\)). After the reaction, the combined mass of the two products obtained is 13.2 g. Assuming quantitative conversion, calculate the mass of 1‑butanol and the mass of 2‑butanol originally present in the mixture.
