Why lone pair occupy more space than bond pair?
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.
Which would have the largest effect on a neighboring bond angle?
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.
Why does lone pair of electrons occupy more space?
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.
What shape is a 2 bonded and 2 lone pair?
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.
When shape would a molecule with two bound groups and two lone pairs have?
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.

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.

How many lone pair and bonding pair in phosphine?
In phosphine (PH3), there are three lone pairs and three bonding pairs.
Why does a lone pair of electrons occupy more space on an atom?
It doesn't exactly occupy more space, but it has a different shape to a bond pair. In a bond pair we have two positive nuclei, with most of the density of the bonding electron pair between the atoms. The outer nucleus attracts the bond pair outwards from the central atom. In a lone pair there is only the central atom to attract the electrons, so they are pulled in more than the bond pair, producing a fatter, squatter shape. This means that more of the electron density is near the central atom than with a bond pair, which makes it more effective at repelling the other electron pairs. Thus there is a difference in the amount of repulsion between different sorts of pair, meaning that he angles between them are different too, in the order, from greatest to least, lone pair-lone pair, lone pair-bond pair, bond pair-bond pair.
