Why the repulsion caused by lone pair is greater than bonding pair?
lone pair has more electrons than bond pair
Bond angle of NH3?
107.5 approximately, as the molecule is based on a tetrahedral shape, which should have 109.5 degree bonds, but the lone pair on the N causes the bond angles to be slightly decreased, by about 2 degrees
What is consequence of electron-pair repulsion around an atom?
Repulsion affect the geometry of a molecule.
What takes up more space a lone pair or a single bond?
A lone pair
How many lone pair and bonding pair in phosphine?
3 bond pairs and no lone pairs
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.
How does a lone pair distort a molecular pair?
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 is the change in bond angle down a group when central atom has lone pair?
there is repulsion between lone pair and bond pair for example in water molecule oxygen has lone pair which repells the bond pair due to this bond angle decreases simply ddue to repulsion btween lone pair to lone pair or lone pair to bond pair angle varies
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.

How does a lone pair distort the molecualr shape?
The lone pair creates repulsion between the molecules attached to it and distorts the shape.
What is responsible for the bent nature of NH3?
There are 3 bonding pairs of electrons N - H and one lone pair . The repulsion forces between lone pair -lone pair is > lone pair -bond pair > bond pair - bond pair. So the lone pair causes distortion from a perfect tetrahedron
How you get bond angle of a tetrahedral shape molecule which have 1 lone pair?
Tetrahedral bond angle of a molecule which have a lone pair electron is 107, smaller than regular 109.5, due to the repulsion of electrons of lone pair.
What is the shape of the molecul nitrogen trifluoride?
NF3 has trigonal pyramidal shape. Around nitrogen, there are 1 lone pair electron and 3 bond pair electrons. The lone pair-bond pair electron repulsion is greater than bond pair-bond pair electron repulsion. The angle between N-F bond pairs are 107 degrees
