QUESTION 3 (9 marks) Ethanol can be produced by the fermentation of glucose or the hydration of ethene. a) Describe the production of ethanol by fermentation of glucose by writing a balanced equation and indicating if a catalyst is required. b) Calculate the atom economy for the production of ethanol by fermentation of glucose. Atom economy = c) Interms of atom economy determine which process for the production of ethanol (i.e. hydration of ethene or fermentation of glucose) is greener. d) Identify two principles of green chemistry other than atom economy that make the production of ethanol by fermentation greener than by hydration.
