Waec Model Questions Vol1 2024 Chemistry Question 44
Practice objective / multiple choice question 44 from the 2024 Waec Model Questions Vol1 Chemistry examination.
A 5.00 g sample of a hydrocarbon mixture contains only cyclohexane (C₆H₁₂) and cyclohexene (C₆H₁₀). The mixture is treated with excess bromine water. After the reaction, the unreacted bromine is extracted and found to be 0.020 mol. The initial amount of bromine added was 0.050 mol. (Bromine adds across each C=C double bond in a 1:1 molar ratio.)\n(a) Calculate the mass of cyclohexene present in the original mixture.\n(b) Assuming ideal behaviour, estimate the boiling point of the mixture given the boiling points: cyclohexane 80.7 °C, cyclohexene 83.0 °C. Give your answers to two decimal places.
