Lone pairs occupy more space than bond pairs because they are localized on a single atom and do not have to share their electron density with another atom. This results in a greater repulsive effect on surrounding electron pairs, leading to a more expanded spatial arrangement. Additionally, lone pairs are typically larger and more diffuse than bonding pairs, which are concentrated between two nuclei. As a result, the presence of lone pairs can alter molecular geometry and bond angles.
Lone pairs reduce bond angles because they occupy more space than bonding pairs of electrons. This increased repulsion from the lone pairs pushes the bonding pairs closer together, resulting in smaller bond angles. Additionally, lone pairs are not involved in bonding interactions, so they exert a stronger repulsive force on adjacent bonding pairs, further distorting the geometry of the molecule.
The largest effect on a neighboring bond angle is typically exerted by lone pairs of electrons. Lone pairs occupy more space than bonding pairs, causing the bonds around them to compress and alter the angles between neighboring bonds. Additionally, the presence of electronegative atoms can also influence bond angles by exerting inductive effects, but the impact of lone pairs is generally more significant in distorting bond angles.
Lone pairs of electrons occupy more space than bonding pairs because they are located closer to the nucleus of the atom and are not shared between atoms. This increased concentration of negative charge leads to greater repulsion with surrounding electron pairs, causing them to spread out more. Additionally, lone pairs are not constrained by the need to form bonds, allowing them to occupy more three-dimensional space. Consequently, their presence can significantly influence molecular geometry.
A molecule with 2 bonded pairs and 2 lone pairs adopts a bent or angular shape due to the repulsion between the lone pairs. This arrangement is commonly seen in molecules like water (H₂O). The lone pairs occupy more space than the bonded pairs, causing the bonded atoms to be pushed closer together, resulting in a bond angle of approximately 104.5 degrees.

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 molecular geometry of a molecule with 2 bonded atoms and 3 lone pairs is bent or angular. This arrangement is derived from the VSEPR (Valence Shell Electron Pair Repulsion) theory, which states that lone pairs occupy more space than bonding pairs, causing the bonded atoms to be pushed closer together. The bond angle in this case is typically less than 120 degrees due to the influence of the lone pairs.

A molecule with two bound groups and two lone pairs would have a bent or angular shape. This geometry arises from the repulsion between the lone pairs, which occupy more space than the bonding pairs, resulting in a bond angle that is typically less than 109.5 degrees. An example of such a molecule is water (H₂O), where the two hydrogen atoms are bonded to the oxygen atom while the two lone pairs influence the overall shape.
When a bond is replaced by a lone pair, the electron geometry of the molecule adjusts to accommodate the new arrangement. Lone pairs occupy space and exert repulsive forces on surrounding bonding pairs, often leading to a change in the molecular shape. For example, if a tetrahedral arrangement (like in methane, CH₄) has one bond replaced by a lone pair, the electron geometry changes to trigonal pyramidal (as in ammonia, NH₃). This alteration affects bond angles and overall molecular geometry.
