Bit like asking why are all flowers plants.

alkenes are hydrocarbons that possess a double carbon bond. it is part of the definition of the term: alkenes are hydrocarbons that...
Because they have carbon and hydrogen, by definition, along with at least one double bond.. If it has no hydrogen, like in Cl2-C=C-Cl2, it is considered a chlorocarbon.
