Pearson Edexcel IAL Chemistry AS 5.5 Test for C=C double bonds
Pearson Edexcel IAL Chemistry AS 5.5 Test for C=C double bonds
Practise using bromine water and acidified manganate(VII) observations to decide whether molecules contain a C=C double bond.
How this is tested
- state bromine water changing orange or yellow-brown to colourless for a C=C bond
- interpret no decolourisation as evidence that a product is saturated or has no C=C bond
- compare alkane and alkene observations with acidified potassium manganate(VII)
