Write down the chemical properties of alkanes using ethane C2H6 as an example.

1) Halogenation:
C2H6 + Cl2 = CH3CH2Cl + HCl (reaction under light)
2) Nitration:
C2H6 + HNO3 = C2H5NO2 + H2O (under heating and pressure)
3) Combustion:
2C2H6 + 7O2 = 4CO2 + 6H2O
4) Decomposition:
C2H6 = 2C + 3H2
5) Dehydrogenation:
C2H6 = C2H4 + H2 (when heated in the presence of a catalyst)
In addition, there are several more properties, but they are not included in the basic school curriculum.
