valence bond theory

Asked by  | 12th Sep, 2012, 07:20: PM

Expert Answer:

The valence bond approach  considers the overlap of the atomic orbitals (AO) of the participation atoms to form a chemical bond. Due to the overlapping, electrons are localized in the bond region. The overlapping AOs can be of different types
Sigma bond: s-s, s-p,p-p
pi bond: p-p
 
Often, the bonding atomic orbitals have a character of several possible types of orbitals. The methods to get an AO with the proper character for the bonding is called hybridization.
