Alcohols Flashcards
What series are alcohols in of what
A homologous series of organic compounds
What is the functional group of an alcohol
-OH
What is the general formula of an alcohol
Cn H2n+1 OH
What are the first 4 alcohols of the homologous series
Methanol
Ethanol
Propanol
Butanol
Are alcohols flammable?
Yes
What reaction do they undergo to produce carbon dioxide and water
Complete combustion in air
Are the first 4 alcohols soluble in water and what is there pH
Yes they are and they have a neutral paha
What can alcohols react with to produce hydrogen
Sodium
What is produced when you react an alcohol with oxygen
It is oxidised with oxygen from the air and produces a carboxylic acid
What are alcohols used as
Solvents and fuels
Why are methanol and ethanol used as solvents in the industry
They can dissolve substances water can and can’t dissolve like hydrocarbons oils and fats
What process is used to make ethanol
Fermentation
What does fermentation use and what does this do
It uses an enzyme in yeast to convert sugars into ethanol
And co2 is also produced
What is the best temperature for fermentation to happen and in what conditions
At 37 degrees in anaerobic conditions in a slightly acidic solution
