The lone pair pushes bonding electron pairs away.
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.
Lone electron pairs give the geometry a triangular base.
The electron geometry of SBr2 (sulfur dibromide) is tetrahedral due to the presence of four regions of electron density around the sulfur atom: two bonding pairs with bromine atoms and two lone pairs. However, the molecular geometry, which considers only the arrangement of the atoms, is bent or V-shaped because the lone pairs repel the bonding pairs, altering the shape.
The type of hybridization that leads to a bent molecular geometry with a tetrahedral electron domain geometry is sp³ hybridization. In this case, there are four electron domains around the central atom, but if two of those domains are lone pairs, the resulting molecular shape is bent. An example of this is water (H₂O), where the oxygen atom is sp³ hybridized, leading to a bent shape due to the repulsion between the two lone pairs.

Iodine difluoride (IF2) has a linear molecular shape due to the presence of two bonding pairs and one lone pair on the iodine atom. This arrangement of electron pairs gives it a linear geometry.
The molecular shape of HC2 is linear. There are only two atoms in the molecule and no lone pairs of electrons, resulting in a linear geometry.
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.
