Neco Model Questions Vol1 2025 Chemistry Question 2
Practice objective / multiple choice question 2 from the 2025 Neco Model Questions Vol1 Chemistry examination.
A \(0.5\ \text{mol}\) sample of an unknown monohydric alcohol with molecular formula \(\mathrm{C}_{n}\mathrm{H}_{2n+2}\mathrm{O}\) is dehydrated with concentrated \(\mathrm{H_{2}SO_{4}}\) to give a single alkene. The alkene is then hydrogenated over a Pt catalyst with excess \(\mathrm{H_{2}}\) to give an alkane of molecular weight \(58\ \text{g mol}^{-1}\). Identify the alcohol (its molecular formula and IUPAC name). Subsequently, when the original \(0.5\ \text{mol}\) of this alcohol is completely combusted, calculate the mass of \(\mathrm{CO_{2}}\) produced.
