RP6

• Primary alcohol


  Oxidised firstly to aldehydes and then, if conditions are harsh enough, to carboxylic acids
• Secondary alcohol


  Oxidised to ketones
• Tertiary alcohol


  Cannot be oxidised by potassium dichromate
• Tollens' reagent


  Ammoniacal silver nitrate, forms a silver mirror or black precipitate with aldehydes
• Fehling's solution


  Oxidises aldehydes to form a red precipitate
• Bromine water


  Turns colourless when reacted with alkenes
• Sodium carbonate


  Reacts with carboxylic acids to produce effervescence (release of CO2)
• Acidified potassium dichromate


  Turns green when reacted with primary and secondary alcohols
• Bromine water


  Remains orange when reacted with benzene
• Tollens' reagent or Fehling solution


  Forms a silver mirror or red precipitate when reacted with aldehydes, but not with ketones
• Sodium carbonate


  Reacts with carboxylic acids to produce effervescence, but not with phenols
