Cyclopentadienone pi bonds
WebSigma and pi bonds are formed by the overlap of atomic orbitals. Sigma bonds are formed by end-to-end overlapping and Pi bonds are when the lobe of one atomic orbital overlaps another. Both acquired their names from the Greek letters and the bond when viewed down the bond axis. A sigma bond, \sigma σ, resembles a similar "s" atomic orbital ...

WebDelocalization, Conjugated Systems, and Resonance Energy. The presence of alternating π and σ bonds in a molecule such as benzene is known as a conjugated system, or conjugated π bonds. Conjugated systems can extend across the entire molecule, as in benzene, or they can comprise only part of a molecule. WebCount the number of lone pairs + the number of atoms that are directly attached to the central atom. This is the steric number (SN) of the central atom. SN = 4 → sp³. SN = 3 → sp². SN = 2 → sp. For example, the O atom in water (H₂O) has 2 lone pairs and 2 directly attached atoms. ∴ SN = 2 + 2 = 4, and hybridization is sp³.
