CH2 Revision (Alcohols)

This resource includes all the basic information that is needed for topic 7.4 in WJEC Chemistry.

HideShow resource information
What is meant by volatility?
This is the tendency for a liquid to evaporate.
1 of 9
Boiling temperatures of alcohols?
Since alcohols have an O-H group, they readily hydrogen bond between molecules, they therefore have higher boiling temperatures compares to corresponding hydrocarbons.
2 of 9
What is the boiling temperature of Ethanol?
80 degrees
3 of 9
Are Alcohols soluble in water?
Yes, as they readily hydrogen bond with the water molecules.
4 of 9
Ethane + Steam -- Ethanol conditions
300 degrees at a pressure of 60 - 70 atmospheres
5 of 9
Maximum yield for Ethanol production?
The forward reaction is exothermic so a low temperature is favored, however this also decreases the rate of the reaction. High pressure is favored, but this is expensive. A catalyst would increase the rate of reaction without affecting the yield.
6 of 9
Products for dehydrating an alcohol?
An alkene and water.
7 of 9
Oxidation of primary alcohols
The usual oxidizing agent is acidified potassium dichromate (VI). The alcohol, oxidizing agent and sulfuric acid are heated under reflux. Colour change is orange to green. A carboxylic acid is formed.
8 of 9
Alcohol consequences?
Liver damage
