Alkene are acyclic unsaturated hydrocarbons containing one double bond between
carbon atoms, forming a homologous series with the general formula CnH2n.
A double bond is the covalent bond of two atoms in a molecule by means of two common
electron pairs.
Unsaturated hydrocarbons are open-chain hydrocarbons with double or triple bonds
between carbon atoms.
Unsaturated hydrocarbons are a large group of hydrocarbons in which molecules two or
more carbon atoms are linked together by multiple bonds (double or triple).
A homologous series is a series of chemical compounds of the same structural type,
differing from each other in composition by a certain number of repeating structural
units — the so-called homologous difference.
