Double bond rigidity refers to the restricted rotation around a carbon-carbon double bond due to the presence of a pi bond, which results in distinct geometric isomers. This rigidity is a fundamental characteristic that influences the physical and chemical properties of molecules containing double bonds, such as alkenes.

Double Bond Rigidity

A carbon-carbon double bond is a type of covalent bond where two carbon atoms share two pairs of electrons, leading to a stronger and shorter bond than a single bond. This bond is fundamental in organic chemistry, enabling the formation of alkenes and contributing to the diversity of organic compounds.

Carbon-carbon Double Bond

A pi bond is a type of covalent bond that results from the sideways overlap of p orbitals, which occurs in addition to a sigma bond in double and triple bonds. Pi bonds restrict the rotation of bonded atoms, contributing to the rigidity and planarity of molecules such as alkenes and alkynes.

Molecules containing double bonds

Alkenes are hydrocarbons that contain at least one carbon-carbon double bond, making them unsaturated compounds. They are reactive due to the presence of the double bond, which can undergo various chemical reactions such as addition reactions and polymerization.
