Aldehydes and Ketones

HideShow resource information
What functional group do both aldehydes and ketones have?
C=O
1 of 11
Where is the functional group located on an aldehyde?
At the end of the carbon chain
2 of 11
What does an aldehydes name end in?
-al
3 of 11
What determines the prefix of an aldehydes name?
The number of carbons on the carbon chain
4 of 11
How do you produce an aldehyde? State the reactants and conditions
Gently heat a primary alcohol with an oxidising agent eg acidified potassium dichromate (VI)
5 of 11
Can an aldehyde oxidise further?
Yes, will produce a carboxylic acid
6 of 11
Where is the functional group on a ketone?
In the middle of the carbon chain
7 of 11
What does a ketones name end in?
'one' (need to number carbon chain to show where functional group is)
8 of 11
How do you produce a ketone?
Reflux a secondary alcohol with an oxidising agent eg potassium dichromate (VI)
9 of 11
What is the benefit of refluxing?
Ensures no volatile organic substances are lost as vapours are condensed preventing them from evaporating and being lost
10 of 11
What is the purpose of distillation?
To purify volatile liquids - separates liquid from any impurities eg unreacted starting materials, catalysts
