Test for alkenes
Add bromine water and shake - electrophilic addition occurs
1 of 6
Test for halogenoalkanes
add NaOH, acidify with HNO3, add AgNO3 - precipitate of AgX occurs
2 of 6
Test for alcohols
add acidified potassium dichromate (K2Cr2O7) - orange to green which primary+secondary alcohols
3 of 6
Tests for aldehydes
Tollens solution - silver mirror, Fehlings solution - blue turns brick red
4 of 6
Test for Carboxylic acid
add NaHCO3 - bubbles are seen as CO2 is given off
