Answer 2

CnH2n+2O

Question 3

Answer 3

-ol names where o-h is found on the displayed formula
butanol
ethanol

Question 4

REMEMBER when drawing alcohol

Answer 4

draw bond between O and H

Question 5

ways to make alcohol

Answer 5

fermentation
catalytic hydration

Question 6

fermentation reaction

Answer 6

glucose -> 2ethanol + 2CO2

Question 7

how fermentation works

Answer 7

fermentation of glucose in absence of oxygen (anaerobic) so doesn’t convert to CO2
uses zymase in yeast
30C temp for optimum temperature for zymase enzyme
alcohol content reaches 12% kills yeast and stops fermentation

Question 8

catalytic hydration

Answer 8

Steam, 300C, 60-70 atm., phosphoric acid catalyst

Question 9

fermentation characteristics

Answer 9

from sugars so renewable, slow process, produces impure ethanol, Batch process

Question 10

catalytic hydration
where it comes from
pros and cons of method

Answer 10

uses ethene comes from oil not renewable, faster but needs heat and pressure, pure ethanol, continuous process
