Experimentally it is found to have the value of 117°. The complete lewis diagram shows central "N" sharing two pairs of electrons with one "O" and one pairs of electrons with "C" "L". There are two lone pairs on the oxygen, three lone pairs on the chlorine, and one lone pair on the nitrogen.

Three orbitals are arranged around the equator of the molecule with bond angles of 120 o . Two orbitals are arranged along the vertical axis at 90 o from the equatorial orbitals. The shape of the orbitals is trigonal bipyramidal. Since there is an atom at the end of each orbital, the shape of the molecule is also trigonal bipyramidal.

The shape of the orbitals is planar triangular. Since there is an atom at the end of each orbital, the shape of the molecule is also planar triangular.

It highlights examples like ammonia (NH3), which has a trigonal pyramidal shape due to one lone pair, and water (H2O), which has a bent shape with two lone pairs. Additionally, it discusses sulfur tetrafluoride (SF4) which displays a distorted tetrahedral geometry.

It emphasizes the formation of hybrid orbitals through the mixing of atomic orbitals to create tetrahedral geometry, which enables carbon to form four covalent bonds, enhancing the stability of its compounds.

As a result, VSEPR does not give correct geometries for these transitional metal complex compounds.. For example, [SeCl 6 ] 2- , [TeCl 6 ] 2- ,and [BrF 6 ] - are predicted to adopt pentagonal bipyramidal geometries according to VSEPR since the central atom can have seven electron pairs.

Molecular shapes are important in determining macroscopic properties such as melting and boiling points, and in predicting the ways in which one molecule can react with another. We will concentrate on several rules based on Lewis diagrams which will allow you to predict molecular shapes.
