Lone pairs typically have the greater repulsion because lone pairs want to be as far apart from one another as possible, even more so than bonding pairs. This is because the lone pairs consist of free-moving electrons.

How does a lone pair 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.
Why the lone pair-lone pair repulsion is more than bond pair-bond pair?
In bonded pairs of electrons the repulsion of the negative charges is somewhat reduce by the positive charge of the bonded atom's nucleus. Lone pairs do not have this.
What are lone pairs in bonding?
because they are not paired....
Why is the water bond angle 104.5 less than the CH4 bond angle 109.5?
in water there are two bond pairs and two lone pairs where as in CH4 there are are four bond pairs nad no lone pair. in ch4 there is only bond pair to bond pair repulsion but in water there are three types of repulsions, lone to lone (greatest repulsion), lone to bond ( lesser repulsion ) and bond to bond ( the least repulsion) , therefore due to the presence of two lone pairs in water the bond pairs are repelled with greater force and they get compressed, reducing the ideal bond angle from 109.5 to 104.5 on the other hand, ch4 has only bond pairs and they dont repel each other that strongly so its angle is greater n its 109.5..
How many lone pairs of electrons are there in the ClO3- ion?
Chlorine (nucleus) has 1 lone pair and 3 polar-covalent bonding pairs (the shared pairs with O). Each oxygen (nucleus) has 3 lone pairs and 1 polar-covalent bonding pair (the shared pair with Cl)
Why does the repulsion between lone pairs are stronger than the repulsion between bonding pairs or between one bonding pair and a lone pair?
Repulsion between lone pairs is stronger because they are closer to the nucleus and repel more strongly than bonding pairs. Lone pairs have less electron-cloud shielding compared to bonding pairs, resulting in increased repulsion. This leads to lone pairs pushing each other apart more forcefully than bonding pairs do.
Why the lone pair lone pair repulsion is maximum?
Lone pair-lone pair repulsion is maximum because both lone pairs are localized around the same atom, leading to a strong electrostatic repulsion due to their negative charge densities being in close proximity. This results in a greater repulsion compared to other interactions like lone pair-bonding pair or bonding pair-bonding pair repulsions.

How does electron repulsion determine molecule shape?
Because they push the bonding pairs down. For example in a water molecule, it has 2 lone pairs which push the 2 bonding pairs down to form a V-shaped molecule. Hope this helps
What shape does the molecule SF3 plus have?
The SF3+ molecule has a T-shaped molecular geometry, with three bonding pairs and two lone pairs around the sulfur atom.
Should BH3 and NH3 have the same shape?
NH3's shape is trigonal pyramidal, which has 1 e lone pairs and 3 bonding pairs, while BH3's shpe is trigonal planar, with 0 e lone pair and 3 bonding pairs. It's the force that electron lone pairs exert that pushes the molecules further and the repulsion force of lone pairs that aided in changing the shape of the molecules. Hence, the shape are different ...
How many lone pair and bonding pair in phosphine?
In phosphine (PH3), there are three lone pairs and three bonding pairs.
Why the lone pair-lone pair repulsion is more than bond pair-bond pair?
In bonded pairs of electrons the repulsion of the negative charges is somewhat reduce by the positive charge of the bonded atom's nucleus. Lone pairs do not have this.
Why does SO2 have a different shape to CO2?
SO2 has a bent shape due to its molecular geometry, which is influenced by the repulsion between the lone pair of electrons on the sulfur atom and the bonding pairs of electrons. In contrast, CO2 has a linear shape because there are no lone pairs on the central carbon atom, leading to symmetrical distribution of the bonding pairs.
