|
Alcohols contain the functional group ?OH. |
|
What is the functional group for alochols? Recall the functional group from alcohols from last lesson |
|
|
|
Methanol, ethanol, propanol and butanol are the first four members of a homologous series of alcohols. Opportunities when investigating reactions of alcohols. |
|
What are the names of the first four members of the homologous series of alcohols? Apply the naming process Monkey's Eat Peanut Butter to the first four members of the alcohols |
|
|
|
Alcohols can be represented in the following forms: CH3CH2OH or displayed formula |
|
What are the names and structural formula for the first four members of the homologous series of alcohols? Deduce the structure of the first four alcohols |
|
|
|
Students should be able to describe what happens when any of the first four alcohols react with sodium |
|
What happens when when alochols react with sodium? |
|
|
|
Students should be able to recognise alcohols from their names from given formulae. |
|
Name the following alcohols from their formula:
a) C2H5OH
b) C3H7OH
c) C6H11OH |
|
|
|
Students should be able to describe what happens when any of the first four alcohols react with burn in air |
|
What happens when when alochol burns in air? Demo the reaction of alcohols with sodium. Students can complete the rest of the practicals themselves constructing a table of the products and observations.

|
|
Students should be able to describe what happens when any of the first four alcohols are added to water |
|
What pH solutions are formed when alcohols are added to water? |
|
|
|
Students should be able to recall the main uses of these alcohols. |
|
What are the main uses of alcohols? Tidying away task:
Identify the main use of alcohols (use images to prompt) |
|
|
|
Aqueous solutions of ethanol are produced when sugar solutions are fermented using yeast. |
|
How can ethanol be produced from sugar? |
|
|
|
Students should know the conditions used for fermentation of sugar using yeast. |
|
What are the conditions used during the fermentation of sugar to produce ethanol? |
|
|
|
Students do not need to know the names of individual alcohols other than methanol, ethanol, propanol and butanol. |
|
|
|
|
|
Students are not expected to write balanced chemical equations for the reactions of alcohols other than for combustion reactions. |
