Teaching Alkenes and the Bromine Water Test in GCSE Chemistry

Pupils use the general formula CₙH₂ₙ, explain why alkenes are unsaturated and carry out the bromine water test in context: orange to colourless for alkenes, no change for alkanes. They meet addition reactions with hydrogen, steam and bromine, explain why alkenes burn with a smoky flame, and finish with a hydrogenation reveal linking alkenes to the spreads on their breakfast table.
