1 Oxidation of alcohols, aldehydes and ketones Primary alcohols can be oxidised to form aldehydes which are further oxidised to carboxylic acids. Secondary alcohols can be oxidised to ketones but can then not be oxidised further. Tertiary alcohols can not be oxidised at all. Strong oxidising agents such as acidified Potassium dichromate or weak oxidising agents such as blue Cu 2+ (in Fehlings solution) which are reduced to form orange brown Cu 2 O can be used.

2 Alcohols, Aldehydes and Ketones with acidified Potassium dichromate Propan 1-ol Propan 2-ol 2 Methyl Propan 2-ol Propanal Propanone Start End

3 Alcohols, Aldehydes and Ketones with Fehlings Solution Propan 1-ol Propan 2-ol 2 Methyl Propan 2-ol Propanal Propanone Start End
