Properties of alkene
1) Combustion
Burns in plentify supply of air, it produces carbon dioxide and water.If INCOMPLETE COMBUSTION, it gives soot, carbon monoxide, carbon dioxide and water.
2) Oxidation
(a) ethanol oxidised to ethanoic acid by warming with acidified potassium dichromate.
(b) ethanol can be oxidised to ethanoic acid using air by the bacteria in the air.
3) Formation of esters
Alcohol reacts with carboxylic acids in the presence of a few drops of concentrated sulphuricacid as a catalyst to form esters and water.
