The lone pair on an atom exerts repulsion on bonded pairs of electrons, which can distort the bond angles and contribute to the overall shape of the molecule. In some cases, the presence of a lone pair can cause a deviation from the expected bond angles in a molecule, leading to a specific geometry such as trigonal pyramidal or bent.
A tone pair, or lone pair, of electrons in a molecule can distort its shape by repelling the bonding pairs of electrons. This repulsion alters the angles between the bonds, leading to a deviation from ideal geometries predicted by theories like VSEPR (Valence Shell Electron Pair Repulsion). As a result, molecules may adopt shapes such as bent or trigonal pyramidal rather than linear or tetrahedral, respectively. This distortion can significantly affect the molecule's properties and reactivity.
A lone pair of electrons can distort the molecular shape because it occupies space around the central atom and exerts repulsive forces on nearby bonded atoms. Unlike bonding pairs, lone pairs are localized and occupy more space, leading to adjustments in the angles between bonded atoms. This results in changes to the ideal bond angles predicted by VSEPR theory, often causing a distortion in the molecular geometry to accommodate the presence of the lone pair. Consequently, molecular shapes such as bent or trigonal pyramidal can arise from the influence of lone pairs.
The lone pair forces bonding atoms away from itself
The lone pair pushes bonding electron pairs away.
The lone pair creates repulsion between the molecules attached to it and distorts the shape.

Tetrahedral bond angle of a molecule which have a lone pair electron is 107, smaller than regular 109.5, due to the repulsion of electrons of lone pair.
The molecule NBr3 has a trigonal pyramidal shape. It consists of a central nitrogen atom bonded to three bromine atoms, with one lone pair of electrons on the nitrogen atom. The lone pair causes the shape to be pyramidal rather than planar.
A tone pair, or lone pair, of electrons in a molecule can distort its shape by repelling the bonding pairs of electrons.

A lone pair of electrons can affect the molecular shape by repelling bonded pairs of electrons, causing distortions in the molecule's geometry. This can lead to changes in bond angles and overall molecular shape.
The shape would be pyramidal because of the lone pair nitrogen has
Lone pair repulsion affects the molecular geometry of a molecule by pushing other atoms and bonds away, leading to changes in bond angles and overall shape of the molecule.
A lone pair of electrons takes up space despite being very small. Lone pairs have a greater repulsive effect than bonding pairs. This is because there are already other forces needing to be taken into consideration with bond pairs. So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.
in XeO3 ,Xe shows sp3 but shape is pyramidal because of the presence of a lone pair of electrons on the central xenon atom. This lone pair distorts the shape of the molecule making it pyramidal.
A lone pair of electrons takes up space despite being very small. Lone pairs have a greater repulsive effect than bonding pairs. This is because there are already other forces needing to be taken into consideration with bond pairs. So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.
The lone pair repels the electrons of the adjacent bonds more so than does a bonding pair of electrons, so thus alters the molecular geometry of the molecule.
