An industrial chemical company has supplies of propene and propan-2-ol. The company considers using these two processes: * process 1: converting propene to propan-2-ol * process 2: converting propan-2-ol to propene. A chemical equation for process 1 is: \
\\text{C}_3\\text{H}_6 + \\text{H}_2\\text{O} \\rightarrow \\text{C}_3\\text{H}_8\\text{O}{\char"24}$Which condition does the chemical company use in process 1? * A: a pressure of 1 atm * B: phosphoric acid as a catalyst * C: a temperature of 1000 °C * D: aqueous sodium hydroxide as a solvent.
The equation for process 1 shows the molecular formulae of propene and propan-2-ol. Describe the displayed formulae of propene and propan-2-ol.
Why is it correct to describe propan-2-ol as saturated, but incorrect to describe it as a hydrocarbon?
A scientist working for the chemical company makes the following predictions that could affect processes 1 and 2 in the future: * crude oil will be less available and more expensive * plant biomass will be more easily fermented to produce propan-2-ol from sugars. Suggest how each of these predictions would affect the two processes.
