3 of 12
State three advantages of producing ethanol by hydration of ethene
1.Fast rate of reaction 2.The product is pure 3.Continuous process
4 of 12
What does Carbon-Neutral mean?
When there is no net emission of carbon dioxide into the atmosphere
5 of 12
What is the fermentation of sugars?
It is a reaction that turns sugar/glucose into alcohol.
6 of 12
Which enzyme is used as a catalyst during the process of fermentation?
zymase in yeast
7 of 12
Which acids can be used in the hydration of ethene to produce alcohol?
concentrated Sulphuric Acid or concentrated Phosphoric Acid
8 of 12
Write the equation for fermentation?
C6H12O6 = 2C2H5OH + 2CO2
9 of 12
Name this alcohol CH3CH(OH)CH2CH3
butan-2-ol
10 of 12
Why is fermentation theoretically carbon neutral?& Why is it not practically carbon neutral?
As it takes in 6CO2 during photosynthesis and releases 6CO2 during combustion, therefore the is no net release of carbon dioxide. However it is not practically carbon neutral as Co2 will be released during: transportation, making fertilisers, etc.
11 of 12
State whether ethanol is primary, secondary or tertiary& Explain why?
Primary, because there is one alkyl group attached to the C which is also attached to the -OH group
