Why does the repulsion between lone pairs are stronger than the repulsion between bonding pairs or between one bonding pair and a lone pair?

The repulsion between lone pairs are stronger than the repulsion between bonding pairs between one bonding pair and lone pair due to electrostatic interactions.

The Lewis structure of PF3 shows that the central phosphorus atom has how many non bonding and how many bonding electron pairs?
3 bonding pairs and one lone pair or non-bonding pair
An example of a hydrogen bond is the bond between?
A common example of hydrogen bonding is the one between water molecules.Hydrogen bonding is an intermolecular type of bonding, so it occurs when the hydrogen of one molecule is attracted to the lone pairs of either Oxygen, Nitrogen or Fluorine because of their high electronegativity. Since water has two hydrogen atoms bonded to an oxygen atom with lone pairs, the hydrogen bonds occur when a hydrogen of one water molecule is attracted to the lone pairs on another water molecule.what else can you give me on hydrogenHydrogen bonding takes place between the hydrogen and oxygen.
How many lone pairs of electrons are in a nitrogen molecule?
There are 2 non bonding pairs in a nitrogen molecule
Describe the general location of electrons in a covalent bond?
The general location of electrons in a covalent bond is that electrons are shared in pairs between 2 atoms. If 2 electrons pairs are shared, 4 electrons are shared in all. They lie between the two nuclei of the bonding atoms. The shared electrons are typically near the middle of the bond between the 2 atoms, in a covalent bond. They may be slightly closer to 1 atom or the other, due to small differences in electronegativity.
What bonding pattern is normal for nitrogen?
Nitrogen normally makes three covalent bond pairs and has one lone pair remaining.
What is the bond angle of C2H4Cl2?
it's nearly 118.because it has three pair of electron,two bonding pairs and a lone pair.the repulsion between lone pair and bonding pairs is more than the repulsion between bonding pair and bonding pair.so the angle of the bond is 2 degree less than a trigonal planar with 3 bonding pairs (120).
What has the strongest repulsion bonding pairs or lone pairs?
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 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 does the vsepr theory explain for covalent bonds?
VSEPR theory explains the geometry around a central atom in terms of repulsion beween pairs of electrons, pairs involved in bonding and lone pairs.
Determine the idealized bond angle for OF2?
Using VSEPR theory there are 4 electron pairs around the central oxygen , 2 of which are bonding and 2 are lone pairs. These electron pairs repel one another pointing approximately to the corners of a tetrahedron, the bond angle F-O-F would be approx 109.5. Not exactly as the lone pair- bonding pair repulsions are stronger than bonding pair - bonding pair repulsion which would lead to a reduction in the angle. This is observed as the bond angle is known to be 1030
How are the shapes of molecules of polyatomic ions related to the number of electron pairs surrounding the central atom?
VSEPR theory predicts that the electron pairs in bonds and lone pairs repel one another and this gives rise to the shape. Lone pairs repel bonding pairs more than bonding pairs repel one another. It is often taught that electrostatic repulsion is the major cause of this but the man who invented the theory, Prof. Gillespie, says that the repulsion is due to the Pauli Exclusion Principle. See wikipedia link for a reasonable description.
How do you determine the shape of molecules?
The shape of molecules is determined by the number of bonding and non-bonding electron pairs around the central atom. The VSEPR (Valence Shell Electron Pair Repulsion) theory is commonly used to predict molecular geometry based on electron pairs' repulsion. The arrangement of these electron pairs results in different molecular shapes such as linear, trigonal planar, tetrahedral, and more.
What are repelled in the VSEPR teory?
The repulsion is between valence electrons.
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 does the VSERP formula explain molecular shape?
Valence electron pairs will move as far apart from each other as possible. (Apex)
The concept that electrostatic repulsion between electron pairs surrounding an atom causes these pairs to be separated as far as possible is the foundation?
