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.

What effect does a lone electron pair have on molecular shape?
The lone pair pushes bonding electron pairs away.
When the electron pair and molecular geometry are different?
Electron pair geometry considers both bonding and lone pairs of electrons around a central atom, while molecular geometry focuses solely on the arrangement of bonded atoms. This can lead to different geometries when there are lone pairs present; for example, in ammonia (NH₃), the electron pair geometry is tetrahedral due to one lone pair, but the molecular geometry is trigonal pyramidal. The presence of lone pairs affects bond angles and the overall shape of the molecule, resulting in distinct geometries.
What is the shape of GaH3?
GaH3, or gallium trihydride, has a pyramidal molecular geometry. This shape arises due to the presence of a lone pair of electrons on the gallium atom, which causes the three hydrogen atoms to arrange themselves in a trigonal pyramidal formation. This geometry is similar to that of ammonia (NH3), where the lone pair influences the overall shape.
What is the molecular geometry of selenium dioxide?
The molecular geometry of selenium dioxide (SeO2) is bent or V-shaped. This geometry arises from the presence of a central selenium atom bonded to two oxygen atoms, along with a lone pair of electrons on the selenium. The lone pair repels the bonding pairs, resulting in a bond angle of approximately 120 degrees. Thus, the overall structure is trigonal planar in terms of electron geometry, but the molecular shape is bent due to the lone pair.
How does a lone pair distort the molecualr shape?
The lone pair creates repulsion between the molecules attached to it and distorts the shape.
What does a lone pair distort the molecular shape?
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.
How long does a lone pair distort the molecular shape?
A lone pair can significantly distort the molecular shape, particularly in molecules with a central atom that has both bonding pairs and lone pairs of electrons. The presence of a lone pair generally leads to a repulsion that is stronger than that of bonding pairs, causing bond angles to be altered. This distortion is often observed in geometries like trigonal pyramidal or bent, compared to their idealized counterparts. The extent of distortion depends on the number and arrangement of the lone pairs relative to the bonding pairs.
How does lone pairs distort the molecular shape?
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.
