- Organic
- Alkenes
- C=C
- reagant
- Bromine water
- Br2
- Bromine water
- observation
- orange/brown ? colourless
- Alcohol
- R-OH
- reagant
- Potassium dichromate (VI)
- Sulfuric acid
- dioxided
- carboxylic acid
- Carboxylic acid
- R-COOH
- reagant
- Sodium hydrogen carbonate solution
- Sodium carbonate solution
- observation
- bubbles
- gas given off turns limewater milky
- carbon dioxide
- CO2
- carbon dioxide
- Infra-red Spectroscopy
- identify bonds present in organic molecule
- different bonds = different IR spectrum
- IR bonds same
- problem
- used in breath test for drink driving
- C-H bond
- O-H bond in water
- old test
- blow into balloon with Potassium dichromate (VI) crystals
- crystals turned green if alcohol present
- blow into balloon with Potassium dichromate (VI) crystals
- Alkenes
