Explain directional properties of bonds by VB theory.

Answer»

Solution :The covalent bond is formed by overlapping of atomic orbitals. The molecule of hydrogen is formed due to the overlap of ls orbitals of two H atoms. In CASE of polyatomic molecules like `CH_(4), NH_(3), H_(2)`O the geometry of the molecules is also IMPORTANT in addition to the bond formation.
ln `CH_(4)` the shape is tetrahedral & H - C - H bond angle is `109.5^(@), NH_(3)` gas PYRAMIDAL shape. To explain directional poor HYBRIDIZATION of atomic orbitals REQUIRE.
