Testing for Organic Compounds
Organic - built around a chain of carbon atoms
Organic compounds burn when heated:
- They burn in air with a yellow-orange and/or blue flame - greater the proportion of carbon atoms the more yellow and smoky the flame is
- When there's plenty of air, burning a hydrocarbon produces carbon dioxide and water
- If the amount of air is reduced then carbon monoxide and carbon (soot) are produced
- Solid organic compounds will char - surface will get scorched with black marks of carbon
Testing for C=C bonds:
- If your organic compound is unsaturated (double or triple bonds between its carbon atoms) it will decolourise bromine water
- If your organic compound is saturated (no double or triple bonds) the bromine water will stay brown
Finding the empirical formula of an organic compound:
Emperical formula - the ratios of all the…
