What is the functional group of a carboxylic acid?C=O-OH-COOH-CHOQuestion 3 of 14 Loading... 4. In the production of ethanol by fermentation, why is the process done in the absence of air?If air were present the yeast would respire aerobically, producing carbon dioxide and water, instead of ethanolIf air were present the ethanol produced would be impure because it would have gases from the air dissolved in itIf air were present the alcohol would oxidise to make an esterIf air were present the yeast would not be able to survive as they can only respire anaerobicallyQuestion 4 of 14 Loading... 5.

What are the advantages/disadvantages of using the hydration of ethene to manufacture ethanol.Advantages: Uses continuous process which is efficient. Fast rate of reaction. Disadvantages: Uses finite resources, e.g crude oil cane. Uses high temp and pressure therefore high energy input. Impure product.Advantages: Fast rate of reaction. Pure product. Disadvantages: Uses finite resources, e.g crude oil cane. Uses high temp and pressure therefore high energy input. Uses batch process which is inefficient.Advantages: Uses continuous process which is efficient. Fast rate of reaction. Pure product. Disadvantages: Uses finite resources, e.g crude oil cane. Uses high temp and pressure therefore high energy input.Advantages: Fast rate of reaction. Pure product. Uses low temp and pressure therefore low energy input Disadvantages: Uses finite resources, e.g crude oil cane. Uses batch process which is inefficient.Question 9 of 14 Loading... 10.
