Alcohols Flashcards
1
Q
what is the general formula for alcohols
A
C₂H₂n+₁OH
2
Q
list the 2 ways alcohols are manufactured
A
1- fermentation of glucose
2- hydration of ethene with steam
3
Q
describe hydration of ethene
A
-phosphoric acid catalyst used
-reaction takes place at 330℃ at 60-70atm
-reaction is reversible
C₂H₄ + H₂O → C₂H₅OH
ethene + steam → ethanol
4
Q
describe fermentation of glucose
A
ethanol is made by glucose using yeast in the absence of air
C₆H₁₂O₆ → C₂H₅OH + 2CO₂
5
Q
properties of alcohols
A
-they have an OH functional group
