Neco Model Questions Vol1 2024 Chemistry Question 38
Practice objective / multiple choice question 38 from the 2024 Neco Model Questions Vol1 Chemistry examination.
A 5.00 g sample containing 70 % (w/w) 2‑butanol and 30 % (w/w) 1‑butanol is oxidised with excess acidic potassium dichromate. Both alcohols are converted to their carbonyl products (butan‑2‑one and butanal). After reflux, the distillate collected has a volume of 4.0 mL, a density of 0.81 g mL\(^{-1}\) and an average molar mass of 72.1 g mol\(^{-1}\). Determine the percent yield of carbonyl products based on the theoretical amount that could be formed from the original mixture.
