Video clips and animations
- Carbon monoxide 1: an over-view
US public service film about the dangers of carbon monoxide poisoning. YouTube
- Carbon monoxide 2: oxygen transport around the body
How oxygen is transported around the body attached to haemoglobin. YouTube
- Carbon monoxide 3: carbon monoxide interfering with oxygen transport
Brief summary of the effects of carbon monoxide poisoning, including the way it reacts with haemoglobin. YouTube
- Alkanes and alkenes with bromine
Simple demonstration of the effect of liquid bromine on cyclohexane (as a saturated hydrocarbon) and cyclohexene (as an unsaturated hydrocarbon). The commentary states categorically that bromine does not react with saturated hydrocarbons. This is untrue. Bromine will react with saturated hydrocarbons, but only in the presence of UV light, and the reaction is slower. Under normal lab conditions (unless you are in direct sunlight), there isn't enough UV light to make the reaction happen anything like as fast as the reaction with the unsaturated hydrocarbon, but given time, it would react.

Instructions for practical work
I have referred to practicalchemistry.org as a reliable source of instructions for experiments. If you find anything really good from other sources, could you let me know via the address on the about this site page of Chemguide.
- Dehydration of ethanol
Simple practical to make and test ethene by dehydrating ethanol.
- Full list of experiments on the practicalchemistry.org site
There wasn't much else specifically related to alkanes, alkenes and alcohols relevant to the IGCSE syllabus at the time of writing. It might pay you to search the full list, though, in case anything else has been added. If you find anything, could you let me know via the address on the about this site page of Chemguide.
