A delocalized pi bond is commonly found in conjugated systems such as benzene rings or in molecules with alternating single and double bonds like in polyenes. This delocalization leads to increased stability and unique chemical properties.
Benzene has covalent bonds. Each of the six carbons in benzene is sp2 hybridized meaning the ring has both sigma bonds and pi bonds. Benzene is aromatic meaning its pi electrons are delocalized and form a pi system.
A double bond contains 2 pi electrons.
No, pi bonds are not the only delocalized bonds. Delocalized bonds refer to bonds where the electrons are not localized between two specific atoms but spread out over multiple atoms. Pi bonds are a type of delocalized bond, but other examples include aromatic bonds in benzene rings and resonance structures in molecules like nitrate (NO3-).
CO2 contains a pi bond between the carbon and oxygen atoms. CHCl3 contains a pi bond between the carbon and chlorine atoms. AsI3 does not contain a pi bond as it consists of single bonds. BeF2 also does not contain a pi bond as it forms only ionic bonds.
Each nitrogen molecule contains three sigma bonds (which include one pi bond) and one pi bond. So, nitrogen molecules contain one pi bond.
double bond contains one sigma bond and one pi bond triple bond contains one sigma bond and two pi bond

Yes, the pi bonds in NO2- are delocalized. The nitrogen atom has a lone pair that can participate in resonance, allowing the pi bonds to be spread over the entire molecule.
What are lacalized bond
The nitrate ion (NO3-) consists of one nitrogen atom and three oxygen atoms. It features a resonance structure with one nitrogen-oxygen double bond (which includes a pi bond) and two nitrogen-oxygen single bonds, with the pi bond being delocalized over the three oxygen atoms. Therefore, in the nitrate ion, you have one sigma bond and one pi bond associated with the double bond, alongside the sigma bonds from the single bonds. However, it does not contain p bonds in the traditional sense, as the pi bond from the double bond is the primary interaction involving p orbitals.
Because in benzene molecule the pi electrons are delocalized (continuously changing their position within the hexagonal ring), so there are no fixed single and double bonds but are in mid of single and double bond character.
C6H8 has eight pi bonds. This can be determined by calculating the number of pi electrons in the molecule, which is equal to the number of pi bonds. Each double bond contributes two pi electrons, and each triple bond contributes four pi electrons.
An alkene is a type of hydrocarbon that contains a carbon-carbon double bond in its chemical structure. This double bond consists of a sigma bond and a pi bond formed by the overlap of p orbitals from the carbon atoms. Alkenes are unsaturated hydrocarbons and are more reactive than alkanes due to the presence of the pi bond.
