Chemical pi bonds
Webpi bond (green) in ethylene With 133 pm, the ethylene C=C bond length is shorter than the C−C length in ethane with 154 pm. The double bond is also stronger, 636 kJ mol −1 versus 368 kJ mol −1 but not twice as much as the pi-bond is weaker than the sigma bond due to less effective pi-overlap. WebCHEM. III Chapter 9: Theories of Chemical Bonding Valence Bond Theory • Valence atomic orbirals on adjacent atoms atoms overlap • Each pair of overlapping valence orbitaus is occupied by 2 valence electrons to form a chemical bond. • Valence electrons are either involved in bonding between 2 catons (shared bonding pairs) or reside on a single …
