WebA simple alkene contains a pair of carbons linked by a double bond; this double bond consists of a sigma bond and a pi bond. The sigma bond is formed by end-to-end overlap of sp 2 hybrid orbitals, and the pi bond by side-to-side overlap of the p orbitals. A pi bond has two lobes of electron density above and below the plane of the molecule. WebThe table shows four alkanes, their molecular formulae and their structures.

WebTwo reasons: First: if you have a quadruple bond, you don't have a hydrocarbon, because all four bonds on both carbon atoms are to one another. This would just be a hypothetical C2 molecule with no hydrogen whatsoever. More fundamentally: carbon simply doesn't form quadruple bonds with itself or, to my knowledge, with any other element. Web8.1 Alkene and Alkyne Overview. By definition, alkenes are hydrocarbons with one or more carbon–carbon double bonds (R2C=CR2), while alkynes are hydrocarbons with one or more carbon-carbon triple bonds (R–C≡C–R).
