Gce Model Questions Vol1 2019 Chemistry Question 9
Practice objective / multiple choice question 9 from the 2019 Gce Model Questions Vol1 Chemistry examination.
A mixture containing 0.050 mol of 1‑butanol and 0.030 mol of 2‑butanol is treated with pyridinium chlorochromate (PCC), which oxidises primary alcohols to aldehydes but does not affect secondary alcohols. The gaseous butanal formed is collected over water at 25 °C and 1 atm, giving a measured volume of 1.20 L (corrected for water vapour). Assuming ideal gas behaviour, calculate the percentage yield of the oxidation of 1‑butanol.
