What is Molecular Geometry?
The three-dimensional arrangement of atoms in space responsible for the molecule’s shape is called its molecular geometry. It comprises bond angles, bond length, torsional angles, and all other geometrical parameters accountable for the shape of the atom.
It affects the colour, reactivity, polarity, and magnetism of the molecule.

What is Bent Molecular Geometry?
Bent molecular geometry is a kind of molecular geometry in which the central atom has two lone pairs of electrons and is associated with two bond pairs. It is also known as angular or V-shaped. Water (H2O), sulphur dichloride (SCl2), methylene (CH2), and Nitrogen dioxide (NO2) are examples of molecules having a bent geometry.
This section will discuss bent molecular geometry, angle, lone pairs, examples, and hybridisation of bent molecular geometry.

Bent Molecular Geometry Lone Pairs
Bent molecular geometry is a kind of molecular geometry in which the central atom has two lone pairs of electrons and is associated with two bond pairs. It is also known as angular or V-shaped. Water (H2O), sulphur dichloride (SCl2), methylene (CH2) and Nitrogen dioxide (NO2) are examples of molecules having a bent geometry.
- The name bent is derived from the fact that it is not linear but has a distorted bent or v like shape. It has two lone pairs and two bond pairs.
- Due to the presence of lone pairs shape of a tetrahedral molecule is distorted.
- AX2E2 is a general example of a V-shaped molecule. In It, two neighbouring atoms surround the central atom A.

The hybridisation of Bent Molecular Geometry
Water (H2O), sulphur dichloride (SCl2), methylene (CH2) and Nitrogen dioxide (NO2) are examples of molecules having a bent geometry.
The name bent is derived from the fact that it is not linear but has a distorted bent or v like shape.
Calculating hybridisation of water.
Hybridisation = ½ X [(number of valence electron) + (number of monovalent atoms attached to the central atom) – (cationic charge) + (anionic charge)]

Hybridisation = ½ X [6+2-0+0]
Hybridisation = 4
Hybridisation = sp3
- Thus it will have two bond pairs and two lone pairs.
Bent Molecular Geometry Angle
In bent molecules, the bond angle is slightly less than 109.5∘. The decrease in bond angles is because the lone pairs occupy more space than the single bonds. Thus, lone pairs in a bent molecule take more space than the other tetrahedral angles, thus reducing the angle to slightly less than 109.5∘.
