Neco 2018 Chemistry Question 21
Practice objective / multiple choice question 21 from the 2018 Neco Chemistry examination.
A 0.45 g sample of an unknown monohydric alcohol reacts with excess sodium metal to liberate \(0.00375\) mol of hydrogen gas. When the same alcohol is oxidised with acidic \(\mathrm{KMnO_4}\) it yields a carboxylic acid of molar mass \(74\ \mathrm{g\ mol^{-1}}\). The boiling point of the corresponding aldehyde (same carbon number) is \(49^{\circ}\mathrm{C}\). Determine the molecular formula of the alcohol and its boiling point.
