2 1. Reaksi pembakaran / Reaksi oksidasi
CH3-CH3 + 3/2 O2 → 2C + 3H2O CH2=CH2 + 2 O2 → 2C + 2H2O CH≡CH + 1/2 O2 → 2C + H2O CH3-CH3 + 7/2 O2 → 2CO2 + 3H2O CH2=CH2 + 3 O2 → 2CO2 + 2H2O CH≡CH + 5/2 O2 → 2CO2 + H2O

3 2. Reaksi substitusi pada alkana
CH4 + Cl2 → CH3Cl + HCl CH3-CH3 +Cl2 → CH3-CH2Cl + HCl CH3-CH2-CH3 + Cl2 → CH3-CH2-CH2Cl + HCl CnH2n+2 + X2 → CnH2n+1X + HX

4 3. Reaksi adisi pada Alkena dan Alkuna
