Alkenes & Alkynes

Sudha M

Alkenes contain a covalent bond that's composed of one sigma and one pi bond between two carbon atoms. The sigma bond has similar properties to those found in alkanes, while the pi bond is more reactive. The carbon atoms within the covalent bond are sp2 hybridized, forming a planar structure. Rotation round the covalent bond is disfavored, so alkenes form fairly stable isomers counting on the positioning of substituents on an equivalent (cis) or opposite (trans) sides of the covalent bond. These isomers are called diastereoisomers.
