- Cl
- cyclo + water = Pale green
- Br
- Cyclo + water = Orange
- I
- Cyclo = Violet
- Water = Brown
- Chlorine most reactive
- Chlorine oxidises both Br and I
- Cl2 + 2Br- --> 2Cl- + Br2
- Water +cyclo turn orange
- Cl2 + 2I- --> 2Cl- + I2
- Water =brown , cyclo = violet
- Bromine is more reactive than Iodine only
- Br2 + 2I- --> 2Br- + I2
- Water=brown, cyclo=violet
