Solution
Methane is a hydrocarbon which has a single bond. Its formula is CH4.
The characteristic chemical property of methane is the substitution reaction. It is a reaction in which one or more hydrogen atoms are replaced by some other atoms.
Chemical equation:
Ethene is a hydrocarbon containing a double bond. Its formula is C2H4.
The characteristic chemical property of ethene is the addition reaction. It is a reaction in which unsaturated compound (ethene) is combined with another substance to form a single product (saturated compound).
Chemical equation:
