ALCOHOLS 2.0 / 5 based on 1 rating ? ChemistryAlcoholsASAQA Created by: samshCreated on: 01-06-16 14:13 conditions for production of glucose by fermentation temperature of 35. Catalyst of yeast. process - distillation t purify. Anerobic 1 of 14 why is a temperature of 35 degrees used in fermentation? the optimal temperture for yeast to grow and reproduce. lower means lower production and higher could denature and kill yeast. 2 of 14 why is is anaerobic? produce ethanol an carbon dioxide, aerobic condtions produce water and carbon dioxide. 3 of 14 what is a biofuel? A fuel produced from renewable biological resources. 4 of 14 an advantage of a biofuel renewable but not a made from crude oil. 5 of 14 what is acarbon neutral process? A process in which there is no net overall carbon emissions to the atomosphere 6 of 14 what do you get when you distill a primary alcohol? you get an aldehyde 7 of 14 what happens when you put an aldehyde under reflux? you get a carboxylic acid 8 of 14 what happens when you put a primary alcohol under reflux? you produce a carboxylic acid 9 of 14 what happens when you put a secondary alcohol under reflux? you produce a Ketone 10 of 14 When using tollens reagent, what do you expect to see if a aldehyde is present? leave a silver mirror around the test tube (aldehyde has been oxidised) 11 of 14 when using tollens reagent, what do you expec to see if a ketone was present? No change 12 of 14 what would you expect to see when using Fehlings solution when an aldehyde is present? A brick red precipitate 13 of 14 what would you expect to see when using Fehlings solution when a ketone is present? No change 14 of 14
