The chemical bond formed by the sharing of electrons such that atoms gets stability is known as covalent bonding. Because of this bonding atoms
Applications of Valence Bond Theory: Formation of Hydrogen Molecule: Each hydrogen atom has single electron in is orbital. Is orbital of a
Limitations of Valence Bond Theory: This theory could not explain the perfect geometries of molecule such as Ammonia, Methane, Water etc. This
Sigma and PI Bond Sigma Bond: (a) It is formed by the axial overlapping of atomic orbitals containing unpaired electrons. (b) Electron intensity
Valence bond theory do not explain (a) Perfect geometrics and bond angle of the molecule. (b) Magnetic properties of the molecule.
2Py orbital of each oxygen atom is the molecule overlaps axially to form a Sigma bond while 2Pz orbital overlap laterally to form a π bond.
Methane, Ammonia, Water molecule structure is not explained by VBT.
A sigma bond is formed by axial overlap of atomic orbitals along inter nuclear axis.
Difference between Sigma and π bond. Sigma Bond Π Bond 1) Primary bond Secondary bond 2) Electron intensity lies along the axis Electron
