CAIE IGCSE Chemistry 11.4.2 Properties of alkanes as being
Practise alkane properties through combustion equations, fuel products and the limited reactions alkanes undergo with chlorine.
How this is tested
- write balanced complete-combustion equations giving CO2 and H2O as products
- choose correct statements about alkanes burning in oxygen but lacking C=C bonds
- link larger hydrocarbon molecules to greater energy released on combustion
