    • Aldehydes and ketone differences
      • Fehlings solution- heat gently
        • Aldehydes are oxidized by Fehlings solution into a carboxylic acid and the copper ions are reduced to copper (I) oxide
        • Ketones are present when blue colour stays
        • If aldehydes are present it goes from blue to red
      • Tollens reagent
        • aldehydes only are oxidized to carboxylic acids and complex ion into silver ions
        • Aldehydes present- forms a silver mirror
        • Ketones present- no mirror formed
    • Alcohols with dehydrating agents
      • WIth phosphoric acid to form an alkene
      • Elimination reaction
      • Water is produced along with the alkene
    • Distillation
      • seperating technique
      • Seperates them from their different boiling points
    • Heat under reflux
      • Used to heat for a long time
      • Condensor prevents the gas from escaping
    • Purifying an organic liquid
      • 1- put in a seperating funnel
      • 2- add sodium hydrogen-carbonate solution and release the pressure made by the forming of CO2
      • 3-  Allow layers to separate inside the funnel
      • 4- run organic layer into a conical flask and add a drying agent
      • 5- place the liquid in a distillation flask to collect the pure liquid
