Your barrel initially contained 160 litres of oil, with a total mass of 140 kg. It underwent fractional distillation and you have been given one of the fractions (not the full 140 kg). It has the following composition by mass: 2.5 kg of Alkane 1: C8H18 4.0 kg of Alkane 2: C10H22 3.0 kg of Alkene 1: C5H10 1.2 kg of Alkene 2: C7H10 1.4 kg of Hydrocarbon 1: C9H14 and 1.6 kg of Hydrocarbon 2: C6H14. You are trying to make 1-hexene from Hydrocarbon 2: C6H14. Please outline all the chemical reactions to synthesise 1-hexene along with the following information: Equations for the reactions Reagents you need to add Reaction conditions Percentage yields for each reaction Any (useful) side products Purification steps Hazards. Please include at least 4 chemical reaction steps. Extension: From 1-hexene, could you go further and synthesise high-density polyethylene and provide the same information listed above?
