Igcse Model Questions Vol1 2022 Chemistry Question 2
Practice objective / multiple choice question 2 from the 2022 Igcse Model Questions Vol1 Chemistry examination.
A 8.00 g mixture of 1‑propanol (\(\ce{CH3CH2CH2OH}\)) and 2‑propanol (\(\ce{CH3CHOHCH3}\)) is oxidised with potassium permanganate in acidic medium until all the alcohols are consumed. In this oxidation, each mole of 1‑propanol loses four electrons (to give propanoic acid) and each mole of 2‑propanol loses two electrons (to give acetone). One mole of \(\ce{KMnO4}\) accepts five electrons. The experiment uses 10.0 g of \(\ce{KMnO4}\). Determine the mass of 2‑propanol present in the original mixture.
